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

I read the reviews on these magnets, and folks weren't kidding, These are dangerously strong. Definitely not a toy, so, keep away from children. I watched one video review that showed how to get them apart, by putting one on the counter and sliding the other one off. If you are successful separating them, I agree with another reviewer to store them with a piece of wood between. I'm thinking 1/2" your be a good spacing.I'm going to use them to locate where to put a roof vent on my roof. I have a standing seam metal roof, so I'll use a piece of cardboard or wood to position on the outside. Then I'll go inside with the other magnet to locate the position.
