Side by Side Comparison of: Signstek vs MIU COLOR

Came fast, only 1day after i odered!!! It works good as it expected to. Nice night light colour but i dont think i see orange and yellow , just dark and light of these colour : green-blue-purple-red- and white, its okay for me tho.
Abt the air comes out in my opinion : its not strong enough but good for bedroom! If we looking for stronger n bigger capacity then we should go ahead for Honeywell products, i saw some version it could hold like 3.4Gallon of water, good for living room and no need to refill many time a day!
I will attach some photos below so it could help u guys to imagine before u guys gonna buy !

I bought two and love them! But I agree that the oil and water mixed then draining into the bottom area seems crazy because oil floats. I do put several drops of oil in with the water but once back on the base and ready to go, I just lift the top vents and drop essential oil right down the tube into the base below that holds the water. This has made a huge difference! Hopefully this will work for you too!

This diffuser is easy to use. It runs all day long and turns off on it's own when the water is gone and a red light come on to indicate that it is empty. The light is really pretty and muted - not too bright to have on in a bedroom all night. The mist is very adjustable. The only thing I do not care for is the cheap plastic vents on the top, they are hard to move and come off easily. But that feature does help in cleaning it. All in all a very good purchase.

I've tried several & I'm happy with most of them, but this is hands down my favorite! I LOVE that it can run for so long... also, it's not a huge thing for the amount of water it holds! Love that it can go FULL BLAST & really fill a room quickly or just a tiny bit. I have a very large room with vaulted ceilings open to the second floor & it seems to fill the whole room! You can smell the essential oils from the cat walk upstairs!

I also LOVE that I can run it through a lamp timer (like when you go on vacation) so I can be on & off as I choose... Because it has that red on/off switch I can put on 30 mins & off an hour then off all night when we're asleep! I fill it up & just let do it's thing, even if we aren't in the room! With the timer it will run much longer on the low setting... I put 10 drops of OnGuard & it's protecting everyone that goes past that room all day!

Oh, also love that I can spin the top spouts so it points in two different directions or same way... way cool feature!

Happy camper & the price is sooooo right for how great it is!!!

Ive had this diffuser for about a week and I LOVE it!! It lasts so much longer than my other diffusers! It has an option to allow you to control the mist output and on low it will litterally last 20 hours! On high it will last around 8 hours. It also has 2 output spouts which is great, if you have a large open floor plan, you can diffuse air into 2 different room! So far, I have nothing but good to say about this diffuser! I put a little more oil in this one, about 6-8 drops since its bigger, and my house smells wonderful! It also has an option to use the diffuser without the beautiful color changing lights, but I perfer the lights. Highly recommended!

A great water diffuser for the price. I have had my original MIU COLOR 500 ml for almost 3 years and this was the second one I have purchased. It is great for a bedroom or office space. Depending on the season, it can run for almost 24 hours, although at that point you aren't getting much true "diffusing" unless you add more oil. The light choices are very nice, although I typically keep them off.

My experience with this oil diffuser is good. Thanks to its large capacity (300ml), my living room is filled with great smell of aromatherapy essential oil. I have several oil diffusers and this is the only one which mist could be adjusted to high or low. The design is slightly different but it looks more elegant. There are 14 colors and you can choose to let it changes itself or choose a specific color. The time could be set to1hr, 2hr, 3hr or just on all the time. The best part is it has auto shut-off function so it protects from overheating damage.

I purchased this diffuser from very positive reviews. I'm just getting into this arena so because of the reviews I decided to go with it. I am totally pleased. Will recommend and will also purchase another. So far so good ! I'm extremely happy ! Lovin this awesome machine !

Paid regular price, and glad I did! If you're seriously considering the purchase, I do recommend watching the video posted here by another reviewer that takes you through every detail of the product, including how it works. I also bought a starter pack of essential oils to try with it (not included). This has been a great stress-reducer / sleep enhancer for me!

My ONLY con so far is that the white light is in the rotation of colors (you can also select just white, any color, or none). It feels a little bright to me when the white comes back around if I'm trying to sleep, but I just change it to a single color if it bothers me. I'm also still adjusting to it being on during sleep, but was very impressed at how much more relaxed I felt right away.

Arrived promptly, packaged well, and exactly what I expected.

I purchased this diffuser over a month ago, and waited to post this review until I knew for sure how it was going to perform. Bottom line, it works beautifully! I use this in my living room, and it suits my needs for the space just fine. Fragrance output is great. I personally do not fill my diffuser all the way to it's 300ml mark. Instead, I fill it to 200ml. This amount of water lasts long enough for any time setting I have used thus far and it allows for a more concentrated fragrance output. The more water used to fill the diffuser, the more diluted the EO's. 200ml of water will last in my diffuser for most of the entire day. This particular diffuser I received looks identical to the description photo, however, there is no colored light feature to this diffuser (as the title may suggest), only natural light, with high & low settings. The light can be used with the diffuser, or alone, or not at all. This diffuser also features a "constant on" state, aside from it's three timed settings. As far as a "high & low mist intensity"? I haven't located that feature on mine. Not so sure about that...
My diffuser also has different timed settings than it's product description states. Mine includes: 60, 180, 360 & "ON" (Constant). It will shut off automatically if the water level gets too low while running. The mist output is great! I have not had any operational issues at all. Easy to clean, just rinse it out and wipe it down with a dry towel. I do this after every use, and it runs like new, every time. I would highly recommend this diffuser to anyone! I would definitely purchase again!

It just dawned on me that this thing plugs right into the wall, with the cord going all the way up to the unit, and it's full of water. I think I'd rather have an item that uses a power supply in this case, so the mains power isn't right next to water. Also, the power knob won't turn off anymore. It's really rough when you turn it down to the point where it would click off, and it doesn't want to go.

The whole unit needs to be cleaned every few days. I wish the cord unplugged from it to make this easier.

The blue light indicating it's plugged in/running is annoying. You can turn the tank light off, but not that power light. At night, it's excessively bright.I wish there was a way to turn it off. You can't even put tape over it, because the thing is translucent.

Other than that, it's really still working fine after 4 months of use almost every night. It puts out a good amount of vapor. The price wasn't bad either, for such a large tank.

So yeah it has some flaws, but at this price point, it's hard to find something of this capacity, so I'm happy I did.

This humidifier lasts the whole night. It is small enough that cleaning it is not a huge hassle. I use 3 or 4 drops of essential oil in the water every other night or so. The alternating colors through the cut-out designs are nice and soft versus bright, but bright enough to be a really good night light. However, the effect is blown by the incredibly bright light at the turn on knob. It is so bright I have to turn that side away from my bed. The knob light alone could light the whole room. The brightness of the knob light is totally not needed. There is only a small dimple on the front of the knob to know where you have the dispensing speed set. I used a magic marker and drew from the dimple up over the edge so I could see and adjust it quickly. Cleaning is relatively easy. Every few days - a week or less - I take both sections to the bathroom sink and pour the small amount of water left in the bottom out, rinse, scrub it with a the small tip end of a baby bottle brush, refill to top with water and add some bleach to soak several hours - usually all day until I return to go to bed. I drop the stopper in to be soaked also. For the top, I turn it upside down and add some water and use the bigger end of the baby bottle brush to brush the inside as best I can, then rinse, then refill water close to the bottom (which is now on the top side), add some bleach, and leave it balanced in my sink to soak. The spouts at the top are removable - both pieces - for individual cleaning. After soaking, I double rinse all sections and refill the top, close with the stopper, and start use again. I read somewhere - I don't remember if it was the brochure that came with the unit or the description on the Amazon ad - that the upper parts come apart for washing. That is somewhat deceiving. The upper spouts come off and divide into two separate pieces for cleaning, and the upper and lower sections separate, but the only way to clean inside the larger upper part is to use a bottle brush through the one inch filling hole and then soak in bleach or vinegar. I am only giving 4 stars because of the full/empty indicator light being so unnecessarily bright and because the upper section does not open to be sure it is clean. Otherwise, I like it better than any of the many I have had over the years. After trying it a few days, I liked it enough to order a second unit - upstairs and downstairs. Hopefully the manufacturers will eventually work out the glitches.

Thrilled at the capacity of this Essential Oil Diffuser, but aesthetics leave something to be desired. I knew that going in, so can't take a star off for that. The weird way that it gets filled and the difficulty in clean-up is where the star gets taken away. I read the reviews where people were saying that it got filled backward, or words to that effect, but it wasn't until I worked with it that I realized what they meant. Imagine a water cooler at work, where the large water bottle filled with water has to be put onto the relatively small base in order for water to come out -- have the visual? Good, because that's how this Diffuser works. The upper part is removed from the base, gets turned upside down, has the screw-on plug removed, then it's filled with water to the fill line. Essential Oil(s) of choice are added, the plug is returned, then you have to flip the water-filled top over onto the base -- the trick being, it can only fit in ca certain way.And in case you were wondering, if you manage to put it on in *just* the wrong way, the water will spill out all over the base and whatever surface you had the base on. In spite of the potential disaster it poses, this Diffuser unit puts out more vapor and for the longest period of time. Better still, you can choose whether or not you want the colors to light up and change, or if you are more interested in its other qualities.

I like this diffuser. I do. But it does have some design flaws I don't care for...

Let's start with the pros:
- This baby can pump out the mist!!! I mainly use my diffusers as a safe alternative to toxic, household fragrances. I'm a scent junkie and have been trying desperately to find a safe alternative to harmful, home fragrances for years now. I've had several diffusers, but none could really satisfy my desire for a strong, lovely scent carried throughout the open floor plan & high ceilings of the lower level of my home. Until I got this thing! This is PERFECT for large space. However, if you need it for a smaller space it would work as well, because you can adjust the volume of mist coming out. It would just run for a really long time. Which is a bonus in my opinion!

- This thing puts out enough mist that it could easily double as a humidifier when needed. Add some eucalyptus & peppermint oil to the tank during a cold & you'll sleep much more soundly!

The cons:
- This is designed like a humidifier. The top is a large tank that you fill then FLIP onto the base which has a small reservoir of water. I don't like this for 2 reasons. 1.) I always end up dripping water everywhere in the flipping process. It's a mess. 2.) Because of the small reservoir in the bottom, if you don't run it for a day or so, and don't clean out the bottom it gets a kind of mildewy smell for the first 5-10 minutes you turn it on. This usually isn't a problem for me, because I run it CONSTANTLY. But I would still prefer it to not have the reservoir, because it means when I switch my scent some of my old oils are still in there. Which leads me to my next problem...
- Unlike other diffusers I've owned the power cord doesn't unplug from the base. This is an issue for me since the only plug available is behind my couch. So I have to climb over my couch to get to the plugin in order to clean out the reservoir, which is why I don't do it often. :/ This may not be an issue for you if you have an easily accessible outlet or you don't run it at least 2 cycles per day with different scents. For me, it's a huge pain in the rear.
- Like other reviewers have noted, there is a rubber ring that has a tendency to pop off. Again this could be fixed if it wasn't designed like a humidifier. This hasn't been a huge problem for me though, since I have it running constantly. The only time I've had it come off was when I cleaned it out one day & left it laying out to dry rather than immediately refilling it and putting it back on the base. However, I was able to get the ring back on & have used it ever since with no problems. I probably just won't risk it anymore & just keep immediately refilling.

Overall, though, I'd probably buy this again or recommend to a friend with a large space. If it was just for a smaller space, though, I'd probably risk trying something else. The whole flipping it over, making a mess & being unable to easily clean the reservoir have just been huge nuisances for me.

Received this product in a very short period of time. Had a small issue after two weeks with a small seal and I contacted the seller and they were simply astounding in rectifying the problem. The seller is 5 stars, no question. This diffuser lasts for a full 8 hours do to its large capacity. I like the ability to turn the LED lights on and off. The unit puts out a good amount of vapor as well. It's easy to re-fill and get going.

I wish I hadn't had the seal concern, but again, I was just pleased as heck with the sellers service!

Can I buy these scents separately? Got this 3 pack, which is a GREAT VALUE. But I'm not huge on the peppermint. I like the tea tree and lavender though and use it daily with my Ecooltronic diffuser. Haven't noticed any residue build up or anything and like that these are clearly advertised as water soluble since that's the type of diffuser I use. Not sure what I'll buy next, but I don't want to have to buy another peppermint.

Plastic, not wood. But attractive and works well. The beeping as you go though the settings is annoying. Also, don't love that you need to dump out the unused water or it smells musty (but I suppose that's the case with all of them).

I wanted to love this diffuser, but after owning it for a while, it has one little flaw. It is beautiful and I do really like the large capacity, but I couldn't leave it in my bedroom because the splashing of the water is so loud that it sounded like a little stream running through the bedroom. While that is a soft, relaxing sound, it bothered my husband and I had to move this diffuser down to my large living room where the water sound is not as apparent. I use it every day now, and love being able to let it run all day, and even enjoy using the colored lights there (I don't ever use them in other diffusers I own). Just wish I could have this beautiful design in my bedroom.

Would give five stars except for I wish that it had a mode where no light shines from the diffuser at all. It has a mode where the main light is off, however the indicator lights that shows what mode the diffuser is in illuminates the whole diffuser, when no other lights are on. This causes a problem when you need to diffuse at night, and you want a completely dark room.Also the cleaning instructions could be a little more clear. They say in between the citric acid cleanings you can clean the tank with a 'neutral soap'. What is that? I'm not a chemist. Give me a better idea of what you mean by a neutral soap.Other than that, I love the diffuser! Works great otherwise! Love the strong continuous stream of mist that it generates. It has enough tank capacity to run all night! Just what I was looking for. Don't like the smaller wimpy ones that can only emit puffs, or run continuously for only an hour or two, and the mist stream is weak.

I used the unit for about seven hours last night, and still had lots of water in the morning, so it is really great that you don't have to refill it all the time. The product puts out a wonderful mist, but I have a little trouble actually adjusting it. It seems that I can't lower it unless I turn the unit off and back on again. Plus I thought the colors would change as the unit operated, but they stay the same color once you have selected one.I found the instructions to be very difficult to read. And for cleaning, it says to use citric acid, which is a little pricey.It was nice to be able to sleep and not wake up with a stuffy nose, and this is what I bought the product for, so it does work very nicely for me.

This diffuser has some nice features and it has worked well for me so far. I like the fact that it has 3 different times settings or just an "on" option. I also like that the light can be turned off if you want to use in the bedroom at night while sleeping. I also like the cylinder shape of the diffuser and the warm glow of the light is a nice affect a night. What I don't like at all about this diffuser is the fact that the opening for the mist to come out is on one side of the top pointing out of the back of the diffuser rather than being in the center on top. In certain situations, this requires you to turn the diffuser around so that its backside is facing out (in my case I want to put it on a table against a wall on the left of my entry way. This means I have to place the diffuser with it's back side facing out into my entry way so that the mist isn't diffusing into the wall. This leaves the cord for the adapter showing rather than being hidden out of view.) Nitpicking, I suppose but because of these two issues, I wouldn't purchase this particular diffuser again. Also, don't fill the reservoir with the water and oil and then try to plug the adapter into the unit, which is on the bottom of the diffuser. This is tricky and can result in some spilled mixture. The unit does come with a small container to use to fill with the water which eliminates this issue. UPDATE 8/20/15: After using this diffuser a few more times, I realize that I like it more than I thought. It is a large diffuser - holds 300 ml and so it runs for several hours at a time. Also, I discovered that even though the mist comes out of the top of the opposite side of where the control buttons are, I can turn the diffuser around so that the side the mist comes out of is facing my open area rather than blowing into my wall. You can also move the battery pack cord up under the diffuser so it doesn't show. It is quiet and the lettering showing the brand of diffuser and the modes of operation are unobtrusive so it doesn't look like an advertisement for the brand. Much classier than some others I've seen and bought. So now I'd say I would repurchase this and I would recommend it to others.

I like this Signstek 1500ML 1.5L Ultrasonic Air Humidifier LED Color Changing Aroma Oil Diffuser, but I don't love it, that's why I can only give it 4 stars. While it holds a lot of water and can run for a very long time, it is not the most user friendly diffuser I've ever owned. To use this diffuser, you have to remove the top piece from the bottom piece, then turn the top piece upside down and fill it with water and oil. To reassemble the diffuser, you have to turn the bottom piece upside down, place it on the top piece (which is also upside down), secure the two pieces together, then turn the whole unit back right side up. Thankfully once full, the diffuser will operate for several hours. I like the ability to adjust the amount of mist coming out, which lengthens the operating time. The light changing function is also a nice added feature. The colors are soft and soothing and transition nicely from one to another. The dragonfly design is fun and enhances the appearance of the diffuser. I wish the Signstek 1500ML 1.5L Ultrasonic Air Humidifier LED Color Changing Aroma Oil Diffuser was easier to clean, but unfortunately that is another reason I can't give it 5 stars. All in all it's a good product, but with a few improvements, it could be a great product.

**UPDATE** I am revising my review, because this diffuser is now leaking. I got 7 months of use out of it and now I have to toss it out. Keep that in mind when purchasing.

I was so excited for this humidifier to come as it was highly suggested by a friend. I am sorry to say the excitement quickly faded. It has some pros, it holds a lot of water and will stay on for a long time. The designs in the sides are really nice and relaxing when you have the light show on. Also, being able to produce steam from two vents that can be moved it very nice.

Now for the cons. The instructions provided are limited. I found that I had to read through the questions section on Amazon to actually figure out how to get the thing to work properly. It is also difficult to fill. The entrance to the water tank is on the bottom so to fill it you have to pull the tank out of the unit, flip it over and add water. The tricky part is then when you want to add your essential oil. It goes into the same entrance as the water. Because of the steam vents on the top, the tank is not able to be placed on a surface while upside down. So as you are holding it you have to get the oil in. It become more difficult if you want to add more than one oil as you have to keep holding the tank while switching oils. Also, the instructions call for three drops of oil. With that much water there is no way that 3 drops are going to work. I added 10 drops each of three scents and still could barely smell it. The next con is the water that is left in the base of the unit. It is quite a bit and it gets kind of nasty. Make sure you are cleaning it often. And my final con, and this was my biggest issue, is the lights. There is a switch in the back to turn off the light show. However even with those lights off, the power light still produces a very bright blue light that lights up the entire unit. I had to turn it off as it was too bright to sleep with and one of my main uses for this humidifier was to run it while I was sleeping. I have moved my smaller unit back into my bedroom and will keep this one for the living room.

All in all, this is just ok. I will still use it but not the ways I was planning to. I am disappointed and would not but it again.

I really like this humidifier, so much that this was my second purchase. The reason I got the second one was because as I was refilling the tank, the decorative cover slipped off and the full tank fell, cracking the plastic and making it unusable. So, I bought the second one, knowing to be very very careful while filling it. And the same thing just happened again! I filled the tank, screwed in the cap, and, while still holding the full tank over the sink, was carefully turning it upright, and the full tank slide right out, hitting the sink, and cracking in the same area, around the opening where you fill it. I am so disappointed. I have small, arthritic hands, and have tried taking the decorative cover off before filling, but ironically, it is difficult to remove. I still like it, and am not going to rate it poorly, but thought it might save someone else from the same problem.

For Aroma therapy this is a big ZERO . The base has a very small area for water & has a very large water tank that sits on the base unit. The problem is when you put the essential oils in the tank as directed, the oils float on the surface of the water and don't make it in to the base unit until the tank is empty. Therefore you have to put oils in the base before you put the water tank on it.
Other diffusers are designed to have the base act as the water tank letting the essential oils do their work.
On the other hand this makes for a Great cold air humidifier, that is why I gave it 3 stars.

I bought this more as a diffuser than a humidifier. I loved the design itself and thought it was really cool that you could remove the outer cover and choose from 4 different side designs. When its running it is quiet and puts out a good deal of mist. The unit holds a good deal of water and that is where the issue came into play for me using it as a diffuser. You have to put in a ton of drops to equal the amount of water it holds. Because of that I quit using it as a diffuser. This would be a good unit for a small to medium room to use as a humidifier. It could also be well used as a night light for children.

I own 5 different diffusers in different places in my home. This is the only one that the light doesn't turn off when the water runs out. Would not order again.

I do not know if it's the diffuser or the cheap oils that I used but this didn't turn out as I was hoping. I was trying to use this to cover my room that I share with two other guys and this is definitely not keeping up with the infuser my old room mate had. Perhaps it is the oils because the infuser here has no problem or issue with operating and putting off the scent of the oils. Works and functions as designed with no issues.

Esthetically it looks great. Love the lights. However, it does not pump out enough mist for me. I have done everything the manual said and it just isn't what I have experienced with other defusers. I even went online to get some other suggestions but, nothing. :(

I like this but i THOUGHT IT WOULD CHANGE COLORS... sorry for caps but I want ppl for see this clearly as I missed it...THIS DOES NOT CHANGE COLORS... ONLY WHITE.Any oils with color will show through when the light is on or even if the light is off and the room is bright. It does work well however and it is relatively quiet imo. I was it all the time.I would probably recommend purchasing a different one however, from MIU even but this one has some key features that are missing.

I have a 100 ml version of this diffuser. I love it and the price was great. I bought this version because I wanted one that would work in a larger space. When I went to use it out of the box, though, I was frustrated where the hole for the cord was. The hole for the cord is slightly off center to the front of the diffuser. That means the cord is half wrapped around the diffuser and visible when in use. Not too appealing to the eye and a little dangerous to me. I'm sort of wondering if mine is different or a defective version than the one in the photo. Definitely would have rethought my purchase.

I bought three of these as gifts, one I kept. I loved my diffuser until it stopped working after 1 month. I have just sent it back and am waiting for a replacementUpdate: Just received an e-mail stating my return is on it's way. Hoping it will last at least a year and not 1 month.I will keep Amazon posted.The company did respond quickly which is a plus in my book, but when I spend $40 I want it to work.

Both the fill gasket and the water out plug gasket have swelled so much. It's very hard to get the fill cap back on because I need to squish the gasket into the cap recess.

The water out seal (spring-loaded plunger) swelled and now leaks. This isn't a huge deal because if you can flip the reservoir over and put it in place fast enough, you'll probably only leak a few teaspoons of water.

Once I get the gasket in place, the unit works pretty well. As someone else pointed out, the basin get gross from the oils.

Got this item maybe 3 weeks back. This was my hubby and mine's first humidifier and I will say that WOW! This this thing gives off an ample amount of vapor! Felt better waking up (we both have allergies) and my skin felt decent (usually it's incredibly dry!)

So why 2 stars and not 5?
1.) The LED Light is NOT fit to be a night light, by any means! If we didn't cover it with a blacked out piece of tape it would keep us awake but even then we still had to cover the front end with a hardcover book! Despite even those efforts the light was so bright it illuminated the entire mechanism and shone around the room.. not good for trying to go to sleep.

2.) After 2 weeks of using it on and off, the "whisper quiet" motor became a whirring and then the whirring progressed into a by a high pitched electric ringing noise on top of it. Whatever frequency that ringing noise is kept us awake so we just shut it off and don't use it anymore.

This product has some serious promise...
Unfortunately it also has some serious problems...
Some people might be able to accept that, but because
this our bedroom, this is not something we want to keep. Returning it as soon as possible.

I initially really liked this unit. The mist flow control and changing light option was such a nice way to destress. I was disappointed that I had not noticed that essential oils should be water soluble but was okay to live it. I bought this 5 months ago and used it quite a bit at first, due to a tonsillectomy. After recovering I didn't use it as often. I stored it until cold and flu season hit our home and pulled it out to run an antiviral essential oil recipe. When I filled the tank and went to place it back on the base it poured water and oils all over the place! Fortunately, I was still in the kitchen and only had tile and counter tops to dry off, but had wasted my oils and ruined one of my favorite kitchen rugs. It appears that the seal around the cap has gone bad. I may try to see if the cap can be replaced. In the meantime, the unit is completely unusable.

**UPDATE**
It is now making a LOUD humming noise everytime I turn it on. The only thing I can do to make the sound go away temporarily is empty the water from the base, turn the base upside down and shake it 5-10 times. I am not sure why that helps it but it is really annoying. I would NOT buy this again and am looking for a nicer one to replace it.
--------------------------------------------------
I bought this thinking that it would be great for running longer than 3 hours ( I have a smaller one that I LOVE but it only runs for 3 hours). This does diffuse the essential oils very well and it runs for a long time, so I thought it would be great! My biggest complaint is that you can't clean it out when it runs out of water and because it is plastic it absorbs some of the oils so when you run lets say thieves through it and then you want to run orange or peppermint it smells a bit weird for the first little while. Also, when you let it run for more than an hour I find that the area around it on the counter is wet because it tends to "spit" water. It spits the water no matter what level I have it running at. I am going to keep it because it runs longer and it is on a countertop that if it gets wet it is ok, but honestly I wouldn't buy it again. The one I LOVE is smaller (100mL). You can clean it, it diffuses the oils well and it doesn't spit water everywhere. I will be buying more of the smaller ones.

Color continuously changes, you cannot set it on one color. Though the color changing doesn't bother my sleep. There is a plastic o-ring around the resevoir knob and has come off several times. Now I can't find it and the knob won't tighten well. Contacted the company about another and they never responded.

Nov 30, 2014 - Have had this product about 2 months. Wish I'd had more information on it - I wouldn't have bought it. You can't change the pictures around. They are stuck on and you have to turn the diffuser around. Also the plastic retains the smell of oils used and oils get set in an area inside, on the bottom and you can't clean them all out. I empty mine after every use and clean it out. It has a soured smell
combined with the different oils I have used. Rosemary Peppermint is not something to love! If it wasn't too late, I would return the product!!!

July 17, 2015 Have had this 9 months. Will be replacing it. Know what to look for this time! You cannot clean the inside of this. Oil gets into places you cannot clean out. Gets moldy easily and you cannot clean it well. Have to bleach it and I don't like putting bleach in it because the plastic retains all smells! Now the plastic has cracked. It's unusable. WASTE OF MONEY. Do not buy this product. Do your research on your item well.

This diffuser does not let any mist out. It just accumulates inside the plastic ring it comes with, and if you lift the lid off you can see all the mist sitting there. I tried several different ways to use this, I even left the lids off but all that did was spit water all over my counter. I was very disappointed in this product.

I have had two of these now. I clean them regularly as the instructuons state but I have had issues with both units after about 6 months. After 6 months of semi-regular to regular use they start to create less and less mist. I have attempted to adjust the settings and also completing multiple extensive cleaning but nothing seems to help.

Doesn't work but had to prop open to get enough flow ie anything. Just wedged my dropper in between the top and base and it sorta works

It lasted us about 3 months with probably a good amount of time in between when it wasn't even used.. The lights work, still beeps, but when we try to adjust the time it'll be on, you can hear the whirring of the motor and a burnt smell coming from it. I used it for my baby, now it feels like a fire hazard. I really did like it when it worked though, a good aromatherapy humidifier.Update - Tried again a few hours later, the lights now faintly blink and there is no longer a motor whirring sound. We maintained it pretty well. We used lemon to "clean" it as others suggested. Sad it isn't working. Checking the comment threads now to see if there is anything that can be done to salvage it..

I purchased this item back in early November as a Christmas Gift. The lights are cool and it is really easy to use. It worked for about a week extremely well and I was very happy with it. Then after about a week it stopped working. I followed the troubleshooting tips and let it dry out completely before trying again and it was still broken. Kinda wish I would have opened it up and used it instead of giving as a gift so I could have returned it withing the time allowed.

While it was working, it was doing a perfect job; the color changing is a nice looking added feature. But the product stopped working after a couple of months. Dead. Called customer service; although it was perfectly clean and did not had tap water in it, we were instructed to go through some cleaning procedures before we can ask for an excahnge. Cleaning as per instructions did not fix anything. We then honestly just gave up and never spent the time and effort to do many back and forth with customer service to ship this bad product back. It just felt like a pure waste of time. Was it just a bad batch? In any case, we were able to get our old diffusers from our shipment again (years old but working); so no need to look for another new one that would likely have ended in the trash as well.

After I received this product, I began using it almost every day. It was a joy to behold and wondrous on the olfactory nerves. It was everything its product description said it was -- until after about six months, when it decided to stop working. I took it apart and cleaned it (I did not disassemble it), always used filtered or bottled water in it (our Florida well water is too full of who knows what to use it straight from the tap!), and only used high quality lavender essential oils in it while it worked. I had read several reviewers who stated that their units had ceased to work after a while, but I thought to myself, oh, those or just malcontents who love to post negative reviews online. I should have listened. The money I spent on it was wasted. No doubt the sellers know that, since like most people, after it was working fine for the first few weeks, I discarded the box it came in as well as my receipt. I'm sure I could find some way to prove via Amazon records when I purchased it and how, but the effort of going to the mat to do that just seems not worth the trouble. All I can say now is CAVEAT EMPTOR! Read the product reviews, and not just the glowing 5-star ones. Heed the advice of those who say this product does not have a long life span. Waste your money elsewhere, if you insist on getting something like this. Just don't buy this one unless money is no problem for you and you like to spend it on things that work well for a short time, then stop and never work again, EVER!

This broke after 2 weeks of use. Suddenly when I would turn the switch nothing would happen. I'm returning it and hoping to get one that is more reliable

Based on several good reviews and being totally new to essential oil diffusers, this sounded like a reasonably priced diffuser with lots of nice features as a starter diffuser. Worked great for a few days. I loved it. The gauge that was to control the amount of mist never did seem to work. It always ran at highest setting no matter where the dial was. Then within a week the ring around the place where you put water changed position or size...and then the spring cap on the water tank began to leak. Within 2 weeks it was only diffusing a sufficient amount of mist for only an hour or two. By a month, little to no mist and it was essentially dead! Don't waste your money. Like someone else said, I'd love to know of a good diffuser that actually keeps working more than a month or two. Seems to be a common problem in many price ranges. I've done a lot of research in the last few weeks.

Loved this when I first got it for the large water rank and generous output. I did not like the lights as I used it in the bedroom and even though I turned them off, the "night" light version could not be turned off and was a bit bright for sleeping. Not being too light sensitive I could tolerate it. I used it every night and each morning I emptied and dried the unit. Last night when I filled it it no longer worked. No steam. And the lights which I never used would not come on either. The unit is DEAD after less than 30 days of use so it's being returned. I will not be buying another model like this as I was two days from being stuck with a $50 piece of junk. In defense of this product, it seems that a short life span is an issue with many of the electric diffusers. If anyone has a model that has a generous reservoir and that they have used for more than a year, I'd love to hear from you. I do want a diffuser but I want one that is durable enough to make its purchase worth the money I spend on it.

8/17/2005 I didn't know I could edit my original review until today. I had added a comment. I am leaving my star rating at 1 only because I know a lot of people read them. This product does deserve a 5 star review, and I do recommend purchasing it because the company stands behind its product, which I have found to be rare these days.

Someone suggested that a lot of people do not read comments and that I should edit my original review so I copied my comment below into the review, and I suggest that people always read comments in reviews:

MY COMMENT: The replacement arrived a few days ago and is working fine, so far. There have been a couple of changes made to the design that are worth mentioning. One is the nightlight. It is been dimmed by the manufacturer. It is now a soft white light that is perfect. To use it you have to switch off the other rotating lights. The other change is either the amount of water it holds or the rate at which full steam disperses it, as it no longer lasts the entire night (8 hours). I could run the previous one on full blast the entire night and it would still be dispensing steam when I awoke. This one is always out of water when I wake up. Not sure how many hours it lasts on full blast now, but I will turn it down a little bit and see if that makes it last all night. UPDATE TO COMMENT: It does last the night on a lower level and is perfect for my needs. Highly recommend this product.

I was very excited about ordering this humidifier based off the reviews. What a piece of crap! This is so cheaply made and it completely stopped working after one day. What a waste.

I was expecting more, honestly I'm not sure this thing even works like it should. The directions are very basic and really dont give any helpful information. I set it up with water and some essential oils, turn it on and nothing really seems to be happening. It seems to be working, the lights turn on, and there is a little bit of a bubbling noise , but no mist at all like the picture. I tried adding more oil and still doesnt really diffuse into the room. I smell nothing unless I am literally sticking my nose right by the unit. I've tried numerous settings, oils and even overnight. I tried to return but evidently the seller doesnt accept returns. Geez, wonder why.

I purchased this diffuser last summer (2016) and it worked great for a few months. Lately, however, the fan won't come on at times. I go through the steps of unplugging it and plugging it back in several times and even blew some canned air into the fan just in case some dust had gotten in, but still no fan. I'll then try it the next day and it works. I have two other diffusers from Miu Color and they do the same thing. I've had diffusers from other companies and have never had an issue like this.

I was excited to find this diffuser but so disappointed once received and could not get it to work. I even enlisted friends to try it themselves just to see what their results were and they were the same, ie, no mist whatsoever. Water appears to heat and vapor appears in the bowl but never rises through to the air. We went online and read all of Miu's responses to customers (most of which said to try this and try that) and we made a good faith effort to try everything in the book. Still didn't work. Weird, too, that they won't accept returns? Really? For defective diffusers? Amazon was great and made an immediate refund when I contacted them about the defective merchandise. Too bad this diffuser seems to have the same problem for so many customers (read the l- and 2-star reviews) as otherwise it would have been great--if only it worked.

I purchased this several months ago and I liked it so much that I purchased 2 more for friends. Now, mine will not stay on, it is set on 180 minutes and the water tank is full but it turns off after about 5 minutes. So disappointed

Heard good things about this unit. When I received it it actually looked like it may have been used. Turned it on and there was zero mist coming out. Bought another brand with 500ml and love it!

Unit broke right before 6 months warranty was out. Miu customer service requested a short video to demonstrate the problem and confirmed that it looks like major parts wore out. They stated that the expected life of their product was 6 months! Their solution was to try and get me $9 off the price of a new one. I was looking for a repair or replacement considering it was under warranty - my email went unanswered. Thank goodness for Amazon customer service who weighted the situation. Ordering a different brand.
