MagnetPAL 3 Pack Heavy-Duty Neodymium Anti-Rust Magnet, Best for Magnetic Stud Finder/Key Organizer/Indoor and Outdoor Multi Uses, Black with Key Ring (SP-MPM3BK)

I had some of these magnets and I liked them, but I wanted a few more. I made the mistake of purchasing some cheaper magnets that did not have near the hold these do and the magnet already came out of one of the cheaper magnets. It turns out that a good price wasn’t necessarily a good deal. So, I ordered these magnets, knowing what I was going to get. These magnets are great. They are very, very strong. It takes a little effort to remove them off of a surface. The only weakness of this magnet, in certain applications, is its strength. If you put it on a keyring with a lot of keys and rings, it’s going to stick to a lot of metal surfaces that you don’t really want it to stick to and, as I said before, it takes a little effort to pull it off. Standing at ¾ of an inch tall (a little over an inch with the loop at the top) and a little over ½ inch wide, it’s very powerful for its size. To be specific, I think I got .58 inches width; however, I was using a caliper with metal jaws on a very strong magnet. If you want to try something frustrating, I’d suggest you try measuring the diameter of these magnets with metal jawed calipers. If not, I would recommend that you take my word for it. If you are looking for a very strong magnet in a small package, you’ll be happy with this product. As the old adage goes, you get what you pay for. In terms of value, with these magnets, you are certainly getting what you pay for.

Muy útiles, tienen muchísima fuerza. Me sirven para encontrar metal en las paredes de gypsum.

So strong i have to be very careful to keep them away from my memory cards and credit cards. Much better than i expected

I have had at least six different "stud sensors" in the past and have often missed or not found them. With three of these you can find nails or screws and line the stud, works great! I will never go back to the electronic ones again.

These little guys are very strong and latch onto drywall screws very quickly. In many ways, better than a stud finder especially when trying to find the ceiling joists due to fatigue in using a stud finder
