Realth Neodymium Disc Magnets with Holes, 0.98" x 0.19" Hole 0.62" Round Magnets for Research, Industrial & Educational Purposes (MC822)

I needed to install a grab bar in my shower. Normally, I'd find a stud above the tile and transfer the line down to the tile. But the tile is from floor to ceiling and there was no way to find the studs. Took one of these magnets, at the suggestion of a YT video, and put it on a string. Found a screwhead. And then another. Straight edge, pencil, done. You don't want to make a mistake drilling a hole in tile in the wrong place. There's no coming back from that. Worth the price even if I never have to use these again.

Very strong that suited my needs. Must use caution for they will break if you are not careful.

I have purchased similar magnets in the past, and they have always included a washer in between in order to keep the magnets from sticking together. It was very difficult for me to separate these magnets as they came attached together with nothing in between. I had to ask for assistance from my partner to be able to separate these, and once I put them on a surface to test, there was no getting them off. These magnets are STRONG. This is obviously a good thing for most people who are purchasing these, however, it is not good for me, who is unable to take the magnets off the surface that I had mounted them to for testing purposes. Word to the wise: These magnets work VERY well. Don’t mount them onto anything until you have already attached it to whatever you got the magnets for. I do believe that these magnets would be great for DIY magnets, which is what I was trying to do. I had planned to super glue one onto the back of a small photo frame that I had received as a gift, and the other I was going to make a magnet with the same idea as a gift.

I bought 3 sets of ring magnets. They were smaller, weaker than others I have bought. I went to return them and order what I am looking for in the first place. Can’t return. So now I am stuck with these and they just don’t stick. Buy elsewhere, where you can get your moneys worth.

These are boring circle magnets. Not sure what I expected, but certainly more than this. I received two circle magnets. One of them broke within minutes of handling them. The other one is now on my fridge.

Very strong magnets. I used them stacked on top of each other and put them on the on/off button on my Xantrex 2000 inverter that is in the storage bay compartment in my motorhome so that camping/fishing gear won’t accidentally Push the button and turn it off. Picture attached.

Very fragile. Very, very fragile. Letting them clink together is enough to break them into chunks.

They have a strong magnetic attraction to each other and took some effort to separate the two. That is a good thing if that's the intended use.
