Review of Magcraft NSN0617 1/4-Inch by 1/4-Inch Rare Earth Rod Magnets, 20-Count

Got this set of magnets to replace several magnets used to hold pictures on the fridge.This babies are VERY strong - almost too strong.My kids can't remove them from the fridge (maybe a good thing?).But they can hold absolutely anything on the fridge door without sliding, or budging after frequent door opening and closing.Their very small size makes them almost disappear, allowing pictures and whatnot to be easily seen on the fridge door.Great magnets, but be warned about their strength!
