Side by Side Comparison of: Black Hills Gold Source vs Sabrina Silver

Amazing!!!!!! I love this so much with a cleaning liquid as well. I run it three times back to back and it makes your rings (of multiple metals look brilliant). It makes diamonds look bran new like the day you got them full of sparkle and fire. Ive tested this on 4 wedding/engagement rings and everyone has loved it and seen a huge improvement. if you wear your rings when you wash your hands i highly recommend getting an ultrasonic cleaner with a cleaning solution due to the soap grime that builds up and general dirt. I put two caps of the cleaning solution into the water. after i use it i leave the top open to let it dry out between uses. also it is not to aloud. one neg is that in the advertising it said it could run for 30 min but i cant figure out how to make it run for more than 300 sec at a time which is why i just run it three times which seems to be enough for my jewelry. You might need to run it longer if your jewelry has been worn for years or is very dirty.

I was shocked at the effectiveness of this cleaner. You would never know that it is even working because it's so quiet, but I so amazed when my jewelry comes out looking brand new. People have even commented on how pretty a few of my pieces are. Many of these are pieces that were dull from sitting in my jewelry box. I honestly thought they would never come clean but this little sonic machine made it happen. I wish I had purchased one years ago. Seriously, not being paid or bribed for this review. It's my true experience with this machine. PLus,customer service is so sweet and helpful. Great overall experience. I have shared with all my friends and family. If you are looking for a new machine. This is the one to get.

I purchased this unit to aid in speeding up the aging process of small batched e-liquid and I have not been disappointed. Fill to the max fill line, sit my bottles in the water and start my 30min cycle. I love it! If I had one complaint/suggestion it would be that a buzzer of some type be added to indicate an end of cycle. Also a big plus that I've noticed with the 30min cycle is that the water is heated in the process. Very nice!Thanks for a great product!

This device worked, straight out of its box, as advertised.It provides a stainless steel tank with a removable plastic tray and wristwatch holder.First thing we did with it was to have it clean our jewelry and keys, submerged in plain water with a squirt of detergent.Next, we tried making liposoma encapsulated vitamin C from ascorbic acid crystals and lecithin powder in pure water without soap. This, too, proved a success, as far as we are able to judge.We could see, by bubbles, that the oscillator produces three, evenly-spaced nodes, along the axis of the tank.The lighted timer counts total seconds, rather than minutes and seconds, which is fine by us.Input power: 120 VAC, 60 cycles, 50 watts. Output 42,000 MHz, producing and destroying cavitation bubbles that loosen all sorts of grime.

This little ultra sonic cleaner leads the pack hands down in it's price range.I purchased this little dynamo to help take the steep (curing) time off E-Juice that I mix for myself and friends who use modified E-Cigs rather than smoke cigarettes . Putting a new mixture through a 2 hour sonic bath can sometimes take as much as 2 weeks of curing time off the total needed to bring out the full flavor of the mix.While the unit offers no conventional heating element, the temperature of the water rises nicely on it's own due to the process itself, if set to the full 30 minutes on the timer. I am not sure if this is specific to this unit or happens with all sonic cleaners since this is my first experience with one. The warming bath should help the mixing process, or if used as a cleaner - the cleaning process.It boasts an incredible number of timer presets to choose from, something I found in no other model evaluated when deciding on which to purchase. They are as follows:By Seconds: 90, 120, 150, 180, 210, 240, 270, 300(default), 330, 360,540, 720, 900By Minutes: 18, 21, 24, 27, 30The 30 minute timer capability closed the deal for me.As to it's cleaning ability; I have used it to clean jewelry and small objects such as my eye glasses and smaller mixing components - mostly out of curiosity. The jewelry required several sessions, but did end up sparkly and bright. In the machine's defense, they had not been cleaned in years. It did a remarkable job on my eyeglasses, getting the crud out of all the nooks and crannies the first time.All in all a very nice machine, well worth the cost if you have a need for such a device.I recommend without reservation.

1st, I bought this mainly for mixing/steeping DIY liquids for ecigs. I love the 30min timer - handy for eliquid making. It seems to work fine - the foil test showed fairly even holes.Furthermore, when contacting the seller with questions, they were more than helpful - even given my main use for it.It does get VERY hot - both the unit and the water(~120degF). So I prefer to let it sit for a couple hours before doing another session.If I do a lot more mixing though, I may step up to a more industrial type unit.

This cloth works wonders. Some of my jewelry was so dark and dirty, but this cloth did magic. It cleaned it so well and made it shiny. I own a lot of silver, not really gold or brass items, so I only used it for silver items and it works great. Bit of work gets put in if it's really dirty, but the cloth makes it look like your items are new.

I wish I could give it 10 stars. So I was in distress to find out that I had to pay to get my jewelry polish, and I googled different ways to get my tarnished silver and gold pieces. I tried everything but nothing was getting them nice and shinny. So I found this and I bought it and it works, I polished everything and my jewelry looks like new. I love it.

I love this polishing cloth. I used it on silver and copper and it easily removed the tarnish. I also used it on a byzantine chainmail bracelet and it was shining in no time. I gladly recommend it and will order a second one to have on hand.

Absolutely Love this item, Quality is amazing, and shines and buffs like no other item i've had. To be honest it looks just like the piece of cloth laying in every Jewelers counter when you walk in. Very pleased with my purchase, and I know my sterling silver jewelery pieces thank me as well!

We ordered these polishing cloths to use in our estate jewelry store to touch up pieces for our customers or to clean delicate jewelry that cannot be dipped into liquid cleaner. All of our staff give rave reviews for these cloths. They especially like the buffing cloth that is included with the cleaning cloth and really enjoy the large size because it helps to keep their fingers and hands from being stained black from the tarnish (which was a problem with the smaller cloths that do not have the buffing cloth). We have already placed a second order for more.

I've used silver polishing cloths in the past, but this one is the best so far. For example look at the photos of my bracelet. I'm not sure what the steel looking metal is, since the bracelet wasn't expensive enough for it to be sliver, but it does tarnish. The other two are copper and brass. The cloth did a fabulous job on all three metals! The cloth is large enough that I am considering cutting off a third of it to keep in my jewelry drawer for quick touch-ups. The rest is large enough to clean my few silver pieces and brass candle sticks.I'm really pleased I don't have to drag out the messy polishing cream anymore!

UPDATE:I purchased the Ultrasonic Cleaner mainly for my dentures. I have used the cleaner for three days on my dentures.It is difficult to see results in that I have not found any residue or indications that "cleaning" has taken place; however, I will continue using it daily and hopefully I will see satisfactory results soon.I am very pragmatic in following instructions and procedures as a result of being in the US Submarine Service for 25 years where you must follow procedures without deviation as you could cause the sinking of the Submarine and loss of lives of your Shipmates..I printed the tips and instructions you emailed me and follow the tips and also the instruction manual,At your service,Gene

Seems to be just fine. Have used it 3 x now. Silver jewelry cleans very well. I have used a capful of actual cleaner in the machine and started off with very hot tap water and it does better.

Tried the aluminum foil test, it started to disintegrate at about 240 seconds without the plastic basket.I use the basket for my dental braces and it seems to work, came out clean. Will see about the durability after using it everyday for a while.

This unit has much to recommend it, and Black Hills Gold Source has top customer service. It is one of the few in my price range that sports a 30-minute timer, which is great for making liposomal encapsulated Vitamin C. It's a bit of a challenge to pour out the final mixture - tends to splash - but you can adapt to catch the splashes. Very quiet operation.

I just got this cleaner and it took a few tries figuring out how long to put my ring in there to get it sparkly clean but in the end it cleans everything really well. Just set it and forget it for a few minutes. Very easy to use and easy to move from one room to another.

I received the Black Hills GoldSource model 890 Professional Ultrasonic Cleaner on Feb. 26th 2014. Upon opening the package I was pleased at how the product looked. I filled the tank with water, put in my retainers, set the timer and the cleaner started working. That is until July 2nd. So a little over 4 months and the Ultrasonic Cleaner isn't vibrating anymore. Would I by another one? Definitely not it cost too much money to work for a little more than 120 days. After writing the above review I was contacted by Black HIlls GoldSource. The represent agreed that the product should have worked longer than it did and he wanted to send me a new cleaner. One day later I received a new Model 890. The company has stood by their product and that is a very good thing. The warranty period had ended but the rep went above and beyond in his dealing with my situation. My original rating was one star but I have changed that to a 4 star rating because of the actions of Black HIlls GoldSource.

I love the size of the clothe ,I use it after I clean my jewelry with cleaner. I will be reordering soon just to have them on hand for future use.Can these cloths be washed and reused ?

When my mother went into the nursing home, she gave me my grandmothers silverware. The silverware had not been used in decades, it was in bad condition. I ordered the Polishing cloth because of the size of the cloth. I knew I had a lot of work to do to get the silverware cleaned. The cloth was amazing, I did have to wet the silverware with a little water due to the tarnish on them. The cloth did an amazing job. I am proud to use my grandmothers silver everyday !

I love the ease with which these cloths work, and they DO work, instantly. I am not sure the polished effect lasts as long but that's okay with me because this is so much easier to use.

I've never used a polishing cloth and couldn't imagine they would work very well. But this one changed my mind. It works and without a lot of rubbing. I used it on small pieces of silver and brass. I gave it four stars only because I have nothing to compare it to. I've always used creams and liquids to clean silver and brass.

This does the job pretty well on silver jewelry, etc., but it isn't as good as the one I used to death before. It takes more work to get the tarnish off than the old one. Still the cloth is thick and very soft, so it won't harm your silver.

I bought this set for my husband,and he was very happy with it!The case they come in is cute,i just wish there was a little more of something there to protect the discs.It makes a nice gift,of a great collection of movies.

worked decently, cant complain for the price

It doesn't get my jewelry very clean, unless I use dish soap and toothbrushes first.

These don't last. Don't expect more than about a year or two before the control panel fails and/or a component on the circuit board melts down when used for just 15 mins daily. This is the second time I've purchased a model sourced from the OEM Chinese supplier and it lasted somewhat longer than a previous step-down model (without the time setting button). So be aware that these are just cheap Chinese models with a fancy logo applied on the outside. They're not Made in the USA and they're not of high quality. And they're certainly not worth $40-$50 for what is a 30 watt model at 42Kh frequency -- plenty of lower-priced alternatives out there.

It's just okay. Pretty cheaply made (hence the price). Had to run by jewelry through 2 or 3 times, with detergent, to see any results. The water comes out a little cloudy, so I guess some dirt was removed, but I'm underwhelmed.

Bought it for cleaning brass/copper/SS vape mods - works okay, best to leave it on the the maximum timer length OVERNIGHT and let it run. I had to let it run overnight 3 nights in a row until it got really clean. Works great for other things like watches.

Not much difference than using jar stuff to me

This cloth polished some silver items well, however it did not remove tarnish/soil from solid brass furniture drawer handles. They look exactly the same whereas the knobs cleaned up and polished beautifully with Brass liquid polishes.

It works to clean the jewelry there just isn't enough of it and the blue will pill on you.

It's ok but took a lot longer with more elbow grease than anticipated. Used on my Alex and Ani bangles. I have eight and it took an hour and a half. Could be they were just really dirty.

It doesn't work as well as my last one, bought a long time ago from a different manufacturer.

So far this product has done its job in polishing my silver jewelry. I do have to say I was surprised and glad that this slip of paper came with the product in case I did damage my other jewelry, but the product information should have listed the caution label.

So let me clarify. 5 stars for how this works on silver! Used it on jewelry and it worked pretty well. HOWEVER, be aware that you aren't supposed to use this on porous stones. "Like: pearls, opals, coral, lapis, malachite and other soft stones" that's a direct quote from the paper that came with the cloth.I'm a little peeved because it doesn't say this ANYWHERE in the description. Just double checked!! Almost all the jewelry I was going to use this on has lapis. A set my husband got me, all with lapis inlay. I wouldn't have bought this if I'd seen that.

It doesn't seem to be working so well anymore. You can barely hear the buzzing now and when I put my finger in the water, it barely buzzes. I guess it was good while it lasted. Going to look into other options.

I have not been impressed. I have tried cleaning a number of things in this. Nothing seems to come out any cleaner than if you cleaned it by hand. In fact, I would prefer hand cleaning.

I have had this thing for a year. It does a good job of cleaning however its not well constructed. Starting right away the thing literally started falling apart, piece by piece. First the hinges, one at a time, then the lid completely off , followed by cracks around the base. For the longest time I held the lid on with tape. Finally the lip around the tank started breaking off. Then a few days ago, the thing just stopped working. I was probably a heavy user of it, using it on average 5 to 6 times a month. I used water and simple green in the sonic cleaner. I'd recommend spending double the cash and buying one that will last.

Not for EJUICE steeping, Foil test was weak after 2min. Isonic Much better

I purchased this to clean my dentures, I don't have any jewelry to speak of to clean. But I have tried it on my dentures several times with and without cleaning tabs, hot, warm cold water, different time cycles and it did nothing to the dentures, not a thing. They looked exactly as they did when I put them in. This thing might do a fabulous job on jewelry and such, but as a denture cleaner it is not. I will say this. Compared to the last one I purchased, this one is a hundred times better. I put a small piece of aluminum foil in there for a test I had read about and it blew huge holes in it in nothing flat. I guess that is how you tell if is working. I will try it on some old coins to see if it works on them before I throw it away.

Not great. This is very thin. Paper towel would work just as well

I don't like the lint all over my lap or table when I use this polishing cloth.

After the first use the edges of the white inner cloth started to rip. Its a very poor quality fabric. I wont buy this product again

Does OK but didn't clean copper very well , not overly impressed with the product .

Does not polish with ease. I have an old jewelers cloth to measure this new one against and this new one definitely has less polishing agent and thereby less polishing ability. Was hoping for a better product. I tried it on my silverware and my brassware and found it unacceptable.

I used them to clean my jewelry always but actually the quality is not the same I wasted my money, not recommendable at all!!!

I've run the machine maybe a dozen times over two months until the on/off button stop working. I expect the cheap switch failed or it's a poor solder joint. I don't recommend this product until the seller confirms the issue is resolved.

Had to return product - swirling scratches in steel drum wall prove product was used not new. Really yucky since granny is using it for her dentures... I checked with the factory and they said the unit was definitely used. I ordered direct from the factory instead and got an un-used unit that works well

Item was Dead On Arrival. None of the buttons would function and unit would not run a cleaning cycle.

Worked for about 1-2 months and now I can not change the run time of the unit. I can only use the default 3 min time as the buttons do not respond when I press them any more. I have tried everything, unplugging the unit, gently tapping the unit, using a different outlet etc.. but the buttons do not respond anymore. Not too happy about this purchase

Ive had mine for abiut 2 weeks now. Ran it mayhe 10 times. And it quit working. Pretty upset and i would like to speak with someone about getting a replacement asap

It does NOT work!!! I followed the directions precisely, ran the cleaner 3 times (for a total of 15 minutes) on jewelry that was not that dirty, and my jewelry was not cleaned at all. My sister has a different brand and her jewelry comes out sparkling clean after a 5 minute cleaning cycle. In reading the directions, I noticed a few spelling errors which made me wonder about their quality control. Save yourself time and money, buy a different brand. Jorja in CA

Does nothing to clean! DO NOT BUY!

POS

It's not that great at all

I am sorry to say that this did not work at all on silver. I tried it on a tiny vase that is trimmed in tarnished sterling silver. Nothing. I tried it on the lid of a small brass ewer that needs cleaning. Nothing. I then tried cleaning a 1925 silver dollar that is moderately tarnished. I rubbed, and rubbed, and rubbed and only a very little bit of the tarnish came off. I think that it would probably take about three hours of hard rubbing to totally clean it up.Maybe it's just me, but I think that's a little too much work.I think that what is supposed to be the polishing side of this cloth was not treated fully or at all with the silver cleaning chemicals. I know it's only $6.99, but I am returning it. Thank goodness Amazon makes that very easy.

no polish on the cloth...does not perform....at all.

Works poorly on sterling silver. Lots of effort needed to remove minimal amount of tarnish.
