Waterproof Neodymium Bar Magnets with Epoxy Coating, Powerful Permanent Rare Earth Magnets, with Double-Sided Adhesive - 60 x 10 x 3mm, Pack of 12

These magnets come securely packaged with plastic strips separating each magnet, and for very good reason. They say 18 pounds of pull. I'd guess that's underestimated! On my desk, I removed a single magnet and laid it at least 2 feet from the package. As I removed my hand, the single slid across my desk, swiftly joining with the others in the still opened package. The impact broke 2 other magnets, shattering them like glass. My mistake, which I will not repeat! My bad! Handle with care as instructed! They are SUPER magnets!! I'd buy them again in a heartbeat!

This are far from strong or “ dangerous “ going to have to return. A bar Magnet like this should be incredibly strong but these are not. The instructions show handling like they are dangerous strong and they are far from strong. FYI .

Strong magnets. Stick to metal.

I bought these to help adhere a fireplace cover to the front of my fireplace. The magnets that came with the cover are really weak and I had hoped these would be able to hold it in place. There is a thin layer of fabric between the magnet on the cover and these. They hardly hold to the inside magnet (yes, I have the poles correct). If I apply them directly to metal, they stick really well, but if there is anything between, they barely hold. They are also very fragile. I was trying to get the plastic package open and it flew out of my hand. One of the magnets shattered when they landed on the table and another one got a chip in it. While trying to get them stuck to the fireplace blanket, I dropped one from about 18 inches and it broke into 3 pieces. I'd return them, but 3 of them are broken.

My shower doors would sometimes not stay closed tightly. One or both seemed to partially slide open a little bit once in awhile and adjusting the rollers can be challenging. So, I put one of these magnets on door edge where the handle is located using the supplied tape and one on the shower rail. It works great and keeps the door closed. I would recommend to a friend.
