Side by Side Comparison of: Zircon vs CH Hanson vs Qooltek vs Stanley vs Hyperikon

Good item. Helped me to identify wooden vertical studs when fixing Flowwall in garage. Used the deeper setting and followed the clear instructions

it beeps every time I get near it. Ok seriously I had another one for years but it meet a tragic death, I liked it do much when I went to replace it I spent time hunting down this specific one. I have used others now and again with more features that sense pipes and wires and so on but they did not perform their key function of finding studs in the walls like this one can. The last one I had for I think over ten years and the battery never died,.

I've used this device a few times now and so far it works great. Sure makes finding studs much easier and more precise.

The instructions are printed on the item...they basically say to go over the stud keep going a few inches and go back...it's not that hard if you can't figure this out then you shouldn't be hanging heavy objects or whatever you're doing. very well made and clear about the location of the stud and it's options. red light is great to have makes it easy to draw a perfectt line and the included tips are very useful

This thing works great all my TV's on the wall

I actually do love this little thing. It hung on my living room wall for almost 2 weeks before my husband saw it. It is much easier to use than some of the others. I don't have to look at flashing lights, it takes up less room so that enables me to find studs in the closet or other small areas. No it does not find electrical units and such but once I find the studs, I mark it, then get out the one that is "supposed" to find the wires and mark the areas.

For the price, I don't think this can be beat.It is purely a strong magnet with a level. You run the stud finder across the wall until you feel it stick, knock to know the width, and draw lines to guide you with your install.I was able to install a TV wall mount and wall shelving around an apartment with ease.If you're average with tools and handy work like myself (I'm a software engineer by trade) this is a great addition any small tool kit.

This thing is amazing for the price! I will never buy another digital stud finder for $20+ that doesn't work well when something this basic does an even better job. I have probably bought 3-4 of the "nicer" ones over the years and they always broke or worked poorly. Once you know the trick to hang this from fishing line or similar and just let it gently swing from side to side it finds the metal screws or nails in the studs and sticks to the wall like magic. Best Stud Finder you will find for the dollar!!

Tiny device with simple concept but works GREAT! Why should you spend more on an electronic device? This does exactly what you need for far less. Buying it on Amazon saved tons of money since I couldn't find the same available in a store anywhere. They all want to sell you something far more expensive or charge an arm and a leg for buying this from their online storefront. Was directed to this by thesweethome.com review. Love it. Love that it also has a level built in.

This is effective, though it must be stressed that you have to be very sensitive when using this in certain situations.I was very disappointed the first 10 minutes I tried in vain to use this by sweeping it by hand across various walls. I couldn't detect anything that I was comfortable assuming was a stud nail, let alone drilling a hole in my wall based on that assumption.HOWEVER: I found it far easier to hang the device with a simple piece of thread and then just swinging it along the wall. Do not touch the finder with your hands at all.With a string added, it jumped right to the stud nails when I came anywhere close to them. The difference between the two methods is like night and day.It's a simple way to increase the sensitivity and efficiency of this product.To anyone disappointed, give it a shot!

I was surprised that a stud finder could have such high reviews especially since it seems to just be a strong magnet. But now that I've used it, it really is pretty awesome. First of all, it's tiny! I didn't think to check the size before ordering it so I was astonished to open the box and see such a little instrument. It fits nicely in the palm of my hand and doesn't take up much space in our already overflowing tool box. It's also strong as heck. It will yank itself to the nearest screw or nail. I was so fascinated by this that I spent the next several minutes running around my apartment looking for all the studs. Unlike the sensor kind of stud finders, there can't be any false readings with this guy.

This review was edited. After leaving my first negative review, the comapny swiftly contacted me and sent me a replacement along with their new tripod stand. This tool has now meet everything I was looking for. What a great company to deal with!!I was extremely excited for this product to arrive. I believed this was truly going to save me time. Needless to say, my hopes were dashed. The measuring tape completely broke off on the first use. The 3 separate laser settings are nice but it is hard to get the laser in the cross position. Needless to say, I went back to the old fashion way of leveling to finish my project. Another key feature I feel is missing is the ability to simply attach the laser to the wall.

Eminently useful. A little difficult to get the cross shaped laser perfectly leveled but once you do it's very useful. Wish the batteries lasted longer though.

I have only had this tool about 3 days and I have used it for leveling shelves in my shop to putting up cup hooks for keys inside a cabinet. Not only is this a great versatile tool but the mfg. has installed batteries as well as included another set. Of all things there is also a handy small screwdriver with the tool for opening the battery compartment. A full set of levels and a tape measure in metric as well as inch measurements. The more I use this tool, the more good things I find about it. I haven't looked but I would be surprised if this tool is made out of the USA. It is excellent and well worth the money. I am happy to recommend it.

*Update-I gave this 2 stars for my previous review but have since changed it to 5 stars. Not necessarily because of the quality of the product but because of the company. They were very pleasant to work with and stayed in touch throughout the time it took me to figure this out. They even sent a new level which was level this time around. So thank you Qooltek for you assistance.1st Review-This was ok. I love the features but when I got this in, the laser wasn't level so it's been a pain to get it level with longer wall runs. I'm constantly having to adjust the light and using sight to check if the line is actually level. Wish I could've had one come in already set to go. Would've made my shelf installation go a lot smoother.

Okay so I just bought this laser level and i am most impressed!! First of all, it came with a little thank you card from the start up company Qooltek that is working with amazon looking for support. They have mine! when i opened the package, a small screwdriver fell out for the battery compartment, thinking that it was nice of them to include this in the box, come to find out that the laser level already had batteries in it and they gave me an extra set!!!! I couldn't believe it when i opened the battery box to find that there was already batteries in the product and they gave me extras!?!?!! No one does that. Kudos Qooltek. Laser level worked like a charm too! No problems

Level works well and the laser is nicely bright. It was a very nice tool to have when hanging curtains during our latest home remodeling. As a bonus, it comes not only with a set of batteries installed, but also a spare set. My only complaint is that the measuring tape is not flush with the bottom of the level, being up about 1/4 inch from it. Excellent for the price.

I'm a noob diy'er and I loved how easy it was to cut up the dry wall with this. I was expecting it to be much harder. The lines were clean. It's a solid product.

Love the cushioned grip. Sharp teeth stay that way after 2 months of use so far. 4 more xx words.

works well

Great product. Very thick and strong materials. Still hard work cutting the drywall though. Definitely need some muscles!

The Stanley 20-556 FatMax Jab Saw is an inexpensive, well made Jab Saw for probably anyone with a use for such a tool. I was going to say that perhaps a professional should choose a better tool, but because nobody I know sharpens these things and you cut through all kinds of drywall and crap I look at it as mostly disposable once you wear it out.That said, I don't plan on needing another one in the next 10-15 years due to how often I use a tool like this and it's totally sufficiently durable construction.

Jab saws are often used to cut drywall but I found a better use! When planting on your knees, and come across a thumb-thick root and don't want to bother standing and getting a big heavy shovel, this saw blade knife, hacks through roots quickly. Be sure to always put this knife away or put in soil with handle up. The wet conditions will make this knife rust quick so take it inside, or rinse and dry.The price was better than in the big box hardware stores. The large rubber handle is perfect for garden conditions where moisture on a wood handle will cause slipping.

Good deal quick ship

Works as advertised!

4 stars bc it's not 100% accurate, and does not come with batteries..

Have an earlier version that has a flaky switch, so I purchased this to replce/upgrade.

Accuracy is close, but not as accurate as my earlier Unit has been once the flaky switch kept it on.

Beats the old hammer and nail study finding trick by a mile, but it is a very reasonably priced unit for a Harry Homeowner project guy.

I used several models of this product family and this one is by far the best. First of all, it is very compact yet sensitive. The traces are clear. The button is flimsy so I wonder how long it will last . You will have to run it a couple of times to see the exact location of the stud (run both directions) but the accuracy is reasonable.

I am renting an old house with thick plaster walls and I was having trouble finding the studs on just a couple of my walls with my electric stud finder.It did not work well just moving it with my hand. Another customer pointed out to tie a string to it and dangle it by the wall. That method worked just fine.4 stars because this doesn't come with a string and I had to use my shoelace.

This stud finder works exactly as it is supposed to. It is so strong the it can suck magnets often be referred greater from almost 2" away. It works perfectly through extra thick plaster and paint over the dry wall. However because of its small size that means it has a very small footprint also. You almost have to swipe it across the wall as if you were frosting a cake or mowing a lawn. When you do find a nail it is unmistakable that you found it. I have used to message to find nails. The 1st is to hang it from a string in just pass the string along the wall to let the stud finder drag on the surface of the wall and it will stick hard when it finds a nail. The 2nd is to cup it loosely in your hand and pass your hand back-and-forth across the wall until it suddenly grabs hold.The packaging is anything but frustration free and is the old school piece of double-layered plastic molding sandwich between sheets of chipboard/cardboard. Notice in my photo the it is not much taller than a standard size toothpick. See that the entire package is much smaller than the A1 size box, Amazon's smallest box.Over all, does it work? Yes, exactly as advertised and as a perfect backup if you don't want to require batteries. Would I get it for a job site? Absolutely not. Its small size and therefore small footprint makes it too cumbersome to try to use for more then figuring out where to mount something at home. For the home user that May only occasionly have to figure out where the studs are, it is perfect because it can also double as a refrigerator magnet due to its smaller size. Additional note regarding the refrigerator usage: When this thing gets within about 2" of the refrigerator it will jump out of your hand in clean hard. It requires a decent amount of skoal to get it back-off. We have a calendar held to the refrigerator with 3 clip magnets. This stud finder was powerful enough to not only grab the 1st magnet from an inch away, but also pull the other 2 from the refrigerator and hold the calendar in the air while carrying it to another room and passing it through the door.Usage tip: Once you find the 1st stud, have a tape measure extended several feet and let the magnets of the stud finder hold the extended end of the tape as you hold the base end. Now mark every 16 or 24" to figure out approximately where to check for other studs' exact locations. This will make finding studs a little easier.Hint (for those without access to ask a good carpenter / inspector): An easy way to figure out your stud placement is to find the stud nearest the corner of a Room. (Avoid corners with windows or doors nearby, or corners of the house, as this may cause design layout to vary.) Measure either 16 or 24" (most common), and that will be your base measurement to expect in the rest of your house. Also note that exterior walls may have different / closer stud placement and distance than interior walls.Remember: Building code changes with time or materials used or location of wall. Keep that in mind when checking different parts of your home.{Professionals, please don't read this next part.} The quality of work or extra decisions of carpenters impacts placement. (I've seen "the studs are an average of 24 inches", and "as long as they're somewhere closer than 16 inches we're fine", plus what looks like "We're putting the door / window / outlet right here and that's final! Throw in some extra boards if it doesn't line up with the studs properly. It will be extra solid then, so it's no big deal if it doesn't make sense!") Also, metal doesn't always mean stud. ("Oops! Didn't measure that cut right / cut isn't smooth / didn't place the drywall correctly. But we can just patch it with sheet metal.")+ Measure twice, cut once. This way you don't make mistakes.- Cut once and measure twice. That way you'll know how badly off you were and then finally get a rough idea of how you need to guess better next time.

I was dubious that this small stud finder would work well. But man, it finds everything. Nails, drywall screws, plumbing, electrical lines. I would give it five stars but it finds so much metal in the walls that you can be fooled into thinking islet has located a stud when it hasn't. Magnets are super strong and the finder will hold itself in place on stud nails - if only they were all straight! Great tool for the price: Very compact.

It works but takes time to figure out and can be a slow process. I needed to install 13 closets in a brand new house, purchased this stud finder for the job. If I solely used this stud finder, it would have taken me a year to complete my project. For a small project this stud finder is great, but for speed, it unfortunately just takes too long to keep searching for the screws.

It's great as a stud finder. Does the job without the bells and whistles. I just can't for the life of me figure out how anyone thought the level in the middle of it would help anyone. The sides of this thing aren't flat... But I purchased it as a stud finder, and it serves that purpose nicely. It does take a bit of extra searching, since you're looking for the nails in the studs, rather than just the giant stud. But that also means that you know exactly where not to drill, if you don't want to hit a nail.

I'm glad I got this stud finder for more reasons than one.First, it'll find a nail in a stud and hang on like a steel trap. It also has a cool feature where if you rotate the level tube, it will show you plumb as well.My construction buddy has one of those high dollar ones with a microchip in it, but for the average homeowner who wants to know whether to use a screw or a molly to hang a picture, or do a little household project, this baby is the one to get.It came on time, with easy to understand instructions, and the price was right.The only downside I can find, and I hate to seem like I'm being picky, but you're supposed to slide it around the wall in an "S" motion.If you're not careful, you'll leave what looks like a pencil mark on white sheetrock.It didn't want to locate nails that were under 1x12 cedar planks that I had already installed.

Make sure that the laser is calibrated before one uses it. Just follow the instructions in the booklet. Read Carefully! The line change occurs when one moves the lens UP or DOWN. Rotate the lens barrel to set the lines. After that procedure, it works perfect and a good value for the price. JMC

Update:After giving it some use for a couple weeks its actualy really handy. Makes me want to get a professional and more accurate version of this, but for the price this one is very good. Changing to 4 stars.This is obviously not meant for professional use since its all made of plastic (even the datum bottom surface) bit for house work this is plenty accurate and handy

Update 10/10/2017:4 months later with very light use, the item broke but the the manufacturer was amazing and responded with courtesy and options. They were really helpful and honest. If you want a cheap level laser with good customer service, I would suggest purchasing from this company.I'm using this device to write in straight lines and not at all for utility purposes. This does not have magnets which allow you to hang it on walls for hanging decorations etc. So far, it has worked exactly as I had hoped it would. The 3 laser modes are extremely nice and easy to use. I just hoped the switch would be different in a way which isn't so easy to accidentally switch in your tool bags or storage space etc.

I like this but wish it were a tad more intuitive. Maybe it will become so overtime. That said, for the price it is a pretty versatile product and I appreciate that it comes loaded with batteries and an extra set, as these are not batteries one is likely to have on hand.Cheers!

Nice little laser level. horizontal, vertical, and a cross lines. 3 settings.

Nice features. Level is handy as a torpedo level, but serves for making the laser level too. Great that it has three beam orientations, horizontal, vertical, and crosshairs. Easily switchable. Only drawback is that its not powerful enough to use outside hardly at all. Beam has good distance indoors. I have several other more expensive lasers for other specific uses, but this is good for quick beams.

Very sharp wish it came with a cover.

This cut was able to cut through dry will like it was bread. Made my job mounting a TV on the wall extremely easy. Only problem is it got slightly damp and rusted overnight. Doesn't effect performance just annoying.

The drywall knife works great but had to buy an extra sheet for hints four stars.

The blade is very rigid making it easy to "jab" though wall board. I recommend using a forceful push as opposed to a jab for safety. The saw teeth are designed to handle wall board very easily and it can be turned in any direction without much effort.Someone just asked if the "cut will be smooth?" Yes, it is made for dry wall. I used it not long ago and it is very easy to control. Bottom line, the hole you cut will be hidden with an appropriate plate to match your connections and the edge of the cut out will be behind the plate.

I bought this to cut thru the false back on a shelf that was made of plywood. It cut thru in no time and left a pretty smooth edge as well. I did drill out a starter hole for it before cutting. Handle was rather comfortable for a hand saw as well.

I was creating a couple of openings for new electrical sockets in my home; I had started them by drilling smaller holes around the area I needed to saw out, and though I was using a fairly sharp drill bit, it was quite a task to drill all the way through the 2-layer, 1" thick drywall I was up against. Enter Fat Max... and I mean that literally. That little sucker tore through that drywall like it was French bread, and I was done with both openings in less than five minutes, with much less effort than I expected it to be. This is my first experience using a saw like this, and its ease of use is already giving me more ideas for home improvement. My landlord will just have to deal with it.....

Not crazy about it. Have to take multiple readings and tapped on wall to confirm.

Works well on walls that are less than 1/2 inch in thickness. I had some difficulty locating studs on thicker walls.

Doesn't work as good as it claims maybe the one up from this level works better but it gets the job done if you're intelligent and kind of know what you're doing

I thought from the advertising that it would read studs through shower stall tile, but not so. It's a bit better than my old stud finder, but not strong enough to penetrate the shower stall tiles. Oh well, at least I tried.

More $ than similar one at Target. Does the job, but is slightly overpriced.

I would use this in addition to a zircon electric stud sensor e50. Many walls in newer houses dont have nails the use glue. This is a magnet that only sticks yo a nail if there is one. Its not going to find a stud fast like the e50 but once you find it you can locate the nails ( if any) so you dont pound a new nail on top of a existing one. Nice idea for the money but does not replace a real stud finder.

This device only seems to work where studs have something metal (nails) in them. The magnet is very strong, but it did not work too well for me. Perhaps it is the framing style of my house behind the drywall..

Takes awhile to get used to how it works but once you get the hang of it, no problem. Have to go real slow. It you're one of those hurry up people, you will lose your mind. It accuracy is what you want, this will find that nail in the stud and hang on it.

This little device is smaller than I thought it would be. Small and easy to use. However, it did not quite work for my needs. I live in a mobile home and was hoping this item would help me find the studs in my walls. However, it was not able to detect the studs. It did detect the screws in the molding, but couldn't find anything past that. It operates solely through magnets, so it does work but did not work for my needs.

I bought this because my father had a magnetic stud finder and they are cheap and simple to use. Problem is, my 1953 house has 1 inch thick dry wall with a 1/8" plaster coating. The magnet on this stud finder is not powerful enough to find most of the studs. I found two in one room, easily, while I think I found a few others by feeling a little pull. In the bathroom is just remodeled, I could find studs. I also tested it on an open wall in the basement and outside a 1/2" or so away, the magnet power weakens.

Good, but not great. Lacks a density finder, only finds magnetic. So we use it with the old one and balance the two off together. Too bad they haven't combined these two.This is The Husband's opinion, given he's the one who has used it to put up a variety of items on new walls in the new downsized home.

Works well; but it needs some kind of switch cover or the switch needs to be more of a positive throw. It's often dead when I pull it from my tool bag because it was leaning against something else and got turned on.

Level works great. The measurements on the bottom are handy. the tape measure is flimsy, so unless you are on a flat surface then you really need a second person to hold it. I have no freaking clue what good the laser is, it just shoots two uneven lines that form an X on an adjacent wall. I guess I was under the impression that the laser would shoot a level straight line. Even though the picture depicts a straight line, I can not get it to make a straight line no matter how I adjust it. Cool idea, could use some improvement.

Bought this for my dad for Dads day, thought it was pretty cool, its okay for some things, but not as versatile as I thought.

Tape measure is only 10'

It does what I needed, but feels a bit cheap.

I was not completely happy with this device; I purchased it for an outdoor project, but the laser is just not bright enough to use out of doors unless one is willing to work at night. That said, it is NOT useless. It is worth the price I paid, and I am sure I find uses for it in the future, just not the one for which it was purchased.

Feels cheap, sharp though. I will put my money into a nicer saw when I wear out this guy.

helped out a lot, but blade bent after a few uses.

messy way to cut dry wall

Very sharp, but the big teeth require a long stroke. Didn't work for what I needed it for but will hang onto it anyway.

Works fairly well, however it was already beginning to rust when it arrived

I've abused this thing badly. I've asked it to do things that it wasn't meant to do. And it's done well. Its okay. But Stanley, like DeWalt, has been going south for a while now... I've smashed out a lot of stuff with this thing for about a year? I'm about to replace it. Its okay, but it ain't great.

not very accurate

Was difficult to use for me. Would beep at different places after passing it over the same section of wall multiple times. Also doesn't come with batteries.

I think it came missing a part. The batteries just rolled around in the housing. Never got to use it, just returned it immediately.

There were several times that it said there was a stud and there was not. I went back to the knock on the wall method and typically find the stud the first time. It is okay...

After opening the package and trying to put the batteries in the casein was weak and would not close but it was an easy return

This is pointless in a house with lathe and plaster. It doesn't get any indication that you are going over a stud, just sticks when it is attracted enough to a screw, which is approximately never in a house with old fashioned lathe and plaster walls. There is a $30 electric stud finder on amazon that works quite well though. I think it is made by Franklin.

It's not a terrible product but it's not really what I had hoped for. The leveler is almost useless and while it found "studs" - you can't really be certain if it's a nail, a pipe, or some other random metal piece in the wall. Great little magnet though but will probably invest in something else next time.

Simply does not work on my walls! I like in a 2 bed room apartment with one living room. This stud finder could not locate one stud in all 3 rooms. I am assuming it isn't powerful enough for my walls or I was sent a dud. Attempting to send back now, although i bought with prime, it says the seller doesn't accept returns....what

This device works as designed. I just don't like the design. I tried to use this a few times and failed to find the stud accurately. Maybe it's user error but I need more information to work with than where a nail is in the drywall.

This thing is so tiny really only good for a tool bag, doesnt work on stucco....best use would be for first timer in an apt hanging pictures it doesnt find wood it finds the metal nail...should be for $5 nothing more way over priced

The low grade neodymium magnet in this stud finder is a simple and much more reliable way of finding studs...UNLESS, your walls are thicker than a sheet of paper. If they are, then you will have to painstakingly comb your walls as slowly as humanly possible, hopefully finding that very slight ping of magnetic attraction. If you don't have the patience (like myself) or don't have the years of stud finding skills (like myself), you will be highly disappointed. Great concept, but the weak magnet is extremely annoying and nearly useless, unfortunately. You might love it; my experience has been disappointing.

When you hear the term laser, you might imagine a beam (projecting a round dot or point) with consistent intensity across a given distance. The reality with this tool is that it has 3 modes: A flat horizontal beam, a flat vertical beam, or both at once (+). Twice the distance gives twice the width (and/or height) of the beam, so it disperses quickly. I had to use this at night to be able to see the projection across only a 9 foot distance outside. It was impossible to see at this distance during the day.

The goodLight in the form of crossThe badLazer too weak for much distance in the outdoor sunThe on off switch toggle can turn on when being transported in tool chestBottom line great for indoor find something brighter for outdoor

intensity faded after a few weeks, even though i kept changing the batteries.. it worked fine for a while, after a while.. you won't be able to see the light. just meh.. wouldn't recommend if you plan on using it for a long time (i need it to "draw" lines on envelopes - calligraphy stuff)

I had accuracy problems with the level of the laser. I bought this to do a list of projects around the house. I got about 2 projects in when I realized the laser was not projecting correctly (ever so slightly off). At first, I thought I had simply made a mistake when my level(s) were off, but after a few issues I come to find the laser is not accurate.

The laser lever does not offer as magnet in the base (it really needs one). The laser is hard to adjust. you can turn the laser but there are no marks to tell you when its at 90-180. So you never really know if its at the right angle.

This looks like a clever 3-in1 device, but unfortunately, it's cheaply built. The tape measure is flimsy, and the bubble levels work about as well as any dollar store plastic level.Most importantly however, the laser level is mostly useless because the orientation of the beam can be changed, (resulting in the beam not going straight up or across). Not really sure why that feature exists when the point is the device is to draw straight, level lines. It comes with a "calibration tool", but there's no way to lock it at plumb level.So if "pretty close" is all you need, then the laser may work for you. Otherwise invest in something higher quality.

I expected better from the other reviews. I haven't used it much, just was using it and it was surprisingly dull. I don't think any of my guys were particularly mean to it from the looks of things.I wouldn't buy it again for professional use, fine for a homeowner.

Rusted after second use

Great little tool, but somehow I managed to bend/kink it in the first few uses. Could use a slightly sturdier blade. But still gets the job done.

cheap

Should come with some kind of cover for th blade - how to store it safely? its very sharp

Looked good when first received. Nasty looking double set of teeth. Tried on cardboard box. It didn't cut well! I was shocked. My comparison was a serrated knife (a small Spyderco folder) that has less leverage but went through like butter. This one struggled a bit and we sent back.

WAS NOT ACCURATE AT ALL. VERY POOR QUALITY.

Did not work. I changed batteries, I tried it on four walls and it did not blink once. Went next door and borrowed my neighbors (another brand) and it located the stud immediately. Threw it in the trash and bought the brand my neighbor has.

I ordered the Zircon StudSensor Pro SL Edge Finder Deep-Scanning Stud Finder with SpotLite Pointing System but that is NOT what I received. Unfortunately I didn't realize this until after I cut open the package and went to use it. I received the Zircon StudSensor SL Edge Finder Stud Finder without the deep scan feature.
Be sure to check the item before opening the package.

I decided to give this product a try despite all the negative feedback. Should have trusted the varying reviews because this product does not work. It worked the very first time i tested to find a stud on the wall and then after that, for some reason, it never found another stud again. Worthless product.

This item did not work at all, but it is not worth my time to send it back for the price. I opened the package slapped a battery in it, and nothing happed I tried 3 different battery's I had laying around and it still didn't work. So I went to the store and got a new battery, the lights would light up then go dim and it still wouldn't find a stud. I will most likely pull it apart just to see how it works (I always wondered what makes these things tick).
Save your money and just use a magnet to find the screws/nails in your drywall. (life lesson learned keep it simple).

I bought this because of all of the glowing reviews...it may be effective to find a stud in some cases...I found it fairly difficult to detect a stud...I did tie a string to it to try it that way...however, I find it useless as a level...it might be 3 inches long and 1 inch wide...would not buy again.

Well this stud finder did not work for me. I'm not sure if it was because I have a mobile home and it can't find a nail for it to work. Would have returned it but lost original packaging. Will see if my son can use it in his home

I guess my house has ONLY 2 studs throughout or this thing is just lying through it's teeth.

I used it to find studs behind a 1/2 inch plaster board. It could not find the studs. For comparison, I used a regular stud finder with lights and it detected the studs correctly. I was not able to use this product as a stud finder. :(Since I could not return it, I am using it as a refrigerator magnet instead. It holds paper very well!!

Magnet is very strong. I have not had good luck with this product, my laser stud finder works much better (and it doesn't work that well).....

This did not work at all for my walls. The Studpop finder i ordered that is also magnet based DID work. I don't believe this magnet is powerful enough.

Laser is dangerous...read the sign before using

Garbage, don't buy. The horizontal bubble level is crooked so when the bubble shows level, the laser is angled upwards by about 2 inches at 6 feet out. No way to adjust this.

Great as a small level but the other functions are confusing to use and not well thought out.

Useless, light on laser is so weak you can barely see it in the dark. If I had not disposed of the packaging I would have returned it.

It's good kinda but it's bad doesn't have a magic to use it on the Mattel !!Don't buy it if you want to use it on the Mattels !!!

A laser level that... well, isn't level. I need to use another level to make sure the laser is level. I might as well attach a laser pointer to my other level. After hanging pictures on the wall and taking a step back, I realized that everything was off. I thought it was weird, so I tried again. Same Result. I did some investigating and realized that the level tube is glued into a hole that is too big. This is making the tube uneven and then the whole thing unlevel. Cool concept multipurpose tool but its basic function is to be a level and it fails at that.

Doesn't have a sheath or anything so I cut myself on it, and then proceeded to throw it in the trash.
