Review on NBZXSYMAG: Unleashing the Power of Neodymium Permanent Scientific Magnets by Joseph Stone

Simply put, these magnets do what you would expect. They hold the Feruss pretty well. I used to buy a few to hang curtains on a steel door and then kind of went crazy. drywall nails? They will magnate. Do the corners of your houses/apartments have steel covers under drywall? These magnets hold it. I currently have a micro machine + 7 bottle caps + two odd square coins + some nails on a magnet hanging from a steel corner post. I bought this as a gift for my builder friend for Christmas. . I'm pretty sure he'll like her. I currently hide them under my steel bed frame, I don't even have to take them out of the box. They just hang around down there. Oh it reminds me WARNING: These are strong magnets and each electronic device attaches differently. For example, they damage your hard drive or your mobile phone. Please be careful when handling these magnets. They can be very funny, but please do NOT forget that they can harm your devices. My take on this is that this is a damn good magnet and if it breaks it becomes two magnets and if they break they become more magnets, it's a kind of gift that keeps giving. Please don't forget my warning, respect these magnets.
