Fantastic little tool.

I've bought 4-5 digital stud finders but every single one of them has either not worked at all or has caused significant mistakes.Don't waste money on a fancy stud finder. This will always work. The only issue is that the magnetic metal ball will likely leave marks on walls painted with lighter colors.

Very easy to use. Easily finds screws or nails in a finished wall

Works just as advertised

Tried it on old and new sheetrock and it latches on to the screws and nails like a champ. Most fasteners were not visible before the test started. Good product.

I had purchased two different types of digital stud finders to try to find studs in our newly purchased home, which is OLD and has plaster and lath walls, those two stud finders were all over the place and very inaccurate with my walls. I looked up other options, watched videos about other methods, etc etc. One simple method suggested was using magnets. I found this Rack-A-Tiers studball and ordered it.It arrived an hour ago, and I've been finding nails/screws, and therefore, studs, behind the thick plaster and lath walls! All over the place! Studs were confirmed by moving the magnet vertically after finding a hit and finding other hits on the same vertical line and marking them... the vertical markings could not be any more clear in indicating a stud, and the spacings of the studs are just about 16 inches apart, confirmed with more vertical lines with multiple hits, marking it all out, it's beautiful.What a simple solution, the most straightforward one. My only gripe is I thought I was getting a pack of those things for some reason, it only comes as a single. Okay, I only really need one anyway. The magnet is just the right strength, it's not TOO strong, and it's definitely not too weak. I am very pleased and now can move forward with our plans!Got plaster and lath walls and need to find studs? Look no further!

Awesome high powered magnet for finding nails/screws! Will but more

Strong enough magnet ball to find wall studs for hanging heavy items. As described.

Wish I had bought one of these years ago. Works faster and easier than both the electronic stud finders I have. Don't think about it, buy it!

Easier to use than my expensive stud finder and finds more studs. I just put it on the fridge or side of metal toolbox. Be careful it is really strong. I dropped it in toolbox and it grabbed 5 items very very strongly.Highly recommend anyone doing renovations and even just hanging heavy items.

Breh, dis lil thang work like a lilol'dawg. The 27 lbs of pull ain't no joke. Im so glad I made the purchase. Yessssir!

I use this for finding screws in finished drywall, and for testing rocks for magnetism

Does as it should. The round ball works better than a flat one. Got yellow. I thought they were all red. Oh well.

This makes a lot of sense and works very well if you know approx how far away the studs are!

The best stud finder I've ever used. I have 3 others and they don't compare to the accuracy of this particular product. I'm building a pantry and needed to find the studs in the walls.

The most simple and accurate stud sensor on the market

Lost my old one and bought another to replace. The magnet is strong and works well to find studs.

Easy to use and very accurate

Very strong magnet, easy to use.

Incredibly easy to use and very accurate in pinpointing nails or screws in drywall. Really helpful timesaver and reduces the mess of ripping out drywall.
