Review on Enhanced Efficiency with Master Magnetics 07254 Magnetic Diameter: Experience the Power of Magnetic Force! by Marcus Merritt

Really exceeded my expectations. Very strong hold. Be VERY VERY careful as I have managed to cut myself with other strong magnets when they met and broke (NOT this particular one). Of course I played with it and wasn't paying attention. Of course, they are considered very strong magnets. Carefully separate the two magnets and wear kid gloves when attaching to a door or window. The trick is to keep the skin away from the door or magnet as they approach. They will crash into each other, and God help you if you have skin between them. In addition, magnets can break when they hit each other, leaving sharp parts (usually breakage occurs between two magnet strikes, not between a metal door and a magnet). Just take your time, be very careful and be aware that you are dealing with an object that can harm you. Much luck!
