5.0 out of 5 stars Dummy-proof
By Solumadur on July 27, 2017
This is easily one of the best gadgets I've purchased. I've used the electronic version of these, often finding the batteries are dead the one time every six months you happen to need it. This one is dummy-proof. There are nails in your wall studs that the strong magnets in the stud finder grab onto. There's a plumb-bob (vertical) and leveler (horizontal) bubble in the center to make sure you've got the stud finder straight. The yellow circle housing the bubble twists depending on which way you're trying to align. Make a pencil mark on your wall and you're set to mount things, hand heavy paintings, etc.
I picked mine up to mount a pull-up bar and gymnastics rings I bought on Amazon Prime Day. I expected it to take at least a few swipes across the wall before the stud finder magnets connected with stud nails, but I got lucky and landed on some immediately. Be aware though that not every bit of metal in your wall is a stud nail. Perhaps most common is the metal protecting corners from floor to ceiling. I actually leave my stud finder on a wall in my home on one of these corners. You'll want to hold the stud finder somewhat gently and move it slowly in a swooping motion until it locks onto a stud. On my walls, it was very easy to tell when you were over a nail, but if you are struggling to feel it, tie a string to your stud finder and let it dangle beside the wall and you'll find a nail. You can then move it straight down or straight up to find other nails on that stud (so you don't run into them with whatever you're hanging). You should be able to find the next stud 16" or 24" inches away. Figure out the correct distance, use a tape measure to mark the studs, then throw the magnetic stud finder up to confirm you're right, and you'll know the studs' locations quickly.

Thanks to this thing, I have a solid, new, exercise setup that I'm enjoying a lot. I don't have a regular need for a stud finder, so the fact that this one is so inexpensive and effective is perfect. I will absolutely buy another if it gets lost.

Hope that's helpful.

5.0 out of 5 stars Great stud finder.
By Mark nunya on July 14, 2018
I use this product to locate and mark studs when installing kitchen and bathroom cabinets. Its the only tool i use. Take it from someone who has installed over 250 cabinets in the last few months.. I get paid per cabinet so moving quickly is a must. This is a huge time saver for finding studs. Electronic stud finders just don't work well in short.. Do your research. I was using a few small rare earth (neodymium) magnets which works well too but they would get lost easily and were harder to hold. A lot of magnets arnt strong enough to grab the screw.. This thing is a good size and the two magnets are very strong (I'll post some pictures). Dropping or even throwing it on The floor won't break it. It's durable like Milwaukee's tools.. Wish they made it in red!! The two magnets are very strong but It won't do damage or leave marks on your wall long as it stays cleab. It having a level inside it is a small plus. It rotates but I wouldn't recommend it for that purpose alone.. just use it before you make your pencil marks so that you know it's not slanted otherwise you will miss it. If you are a professional installing kitchens/ or a DIY hanging picrures looking for a stud finder get this or something that has strong (neodymium) magnets. I know Amazon has a couple other options that use powerful magnets look decent that look decent but just know I read through reviews and all that and I picked this one.

Update/edit (July 25th 2018)

The other reviews are accurate in that these little guys like to jump ship and go into hiding. I lost the first one I ordered. So that brings me to the only negative thing I've found.. Because the magnetic pull is so strong they will gravitate to to anything metal within a few inches It's easy not to notice when your using an impact driver. Either way, I'd like it if they..

1. offered a retractable magnetic belt clip with a pencil as an accessory..

2. Offered a smaller 1 magnet version and a larger 3 to 4 magnet version.

3. Included a string (another method) for a slightly faster process for those that havent learned to guesstimate where the studs will be.

I think they could deff improve this product and should provide more use/job specific options.
Still, I stand by my initial 5 stars.. This is over all the best stud finder out. Might seem like a small thing but it can really hold things up, drain energy, waste time, and money.


-Youtube how to locate studs and safety when drilling. This and the other reviews will give you an idea of where to aim for with the stud finder.. Take 5 minutes upfront to do this and you will save time overall

- the other reviews on here that talk about holding it lightly at first and guesstimate. You have to get a feel for it. Give it a few more patient minutes and it will get very easy.

I've heard people say to attach a string and dangle it on the other end against the wall. Swing it back and forth gently to cover more space till it catches on a screw. Not my preference but some claim it's easier.
