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

People.people.people.listen. It's a magnet that if the moon were made of steel I could stand outside in my backyard and lasso it in my garage in the morning! That's the problem. NOT NECESSARY. NOT NECESSARY. DO NOT place this on the door without the foam packing. He's so damn strong that he can take it. I read many reviews where people couldn't tell and one lady actually stated that it had melted on her storm door. That's strong. When you open the blister pack just be aware and be careful. Once you know where you want to place it, spread it out and make sure the foam disc is between the magnets, even if you're placing it on a door. Be extra careful. I used the box that came in the package. I cut it off and held it between two magnets for protection. To separate them you must SLIDE. It's very, very strong. You have to hold something between two surfaces or you'll ruin something. your door. your finger. your sanity!
