Review on Powerful And Convenient: MIKEDE 10Pack Neodymium Disc Countersunk Hole Magnets With 25 Lbs Holding Capacity And Screws Included by Tom Lawson

These are so strong that you have to be careful where you put them. Metal things nearby can suddenly find themselves attached to the magnet. I couldn't figure out why the directions recommended using gloves when handling these magnets until I detached one magnet then brought it within about 6 inches of the stack of magnets and it decided to violently make its way back to the stack. I also had several instances during my project where I got something metal too close to one of the magnets before I had a chance to secure the magnet, and the magnet went flying onto the metal item.Overall, these are great magnets. Even with my carelessness causing magnets to fly all over the place, none of them broke. And in the end, they worked perfect for my project.
