Review on Powerful DIYMAG Neodymium Cube Magnets- Grade N52, 1 Inch, Pack Of 2 by Derek Dolla

Be warned --these magnets are incredible! I was planning to put them into old socks (like I do with a slightly smaller magnet that I have) to make them easier to remove from surfaces. I managed to pry them apart, but unfortunately I did not realize how strong they are. Thinking that it was a safe distance, I set them down a few inches apart and they immediately slammed together and both shattered. That is not a problem with the magnets --they are very powerful--it's my fault for not realizing how powerful they really are.
