Review on MIKEDE Strong Neodymium Disc Magnets, 16 Pack Powerful Permanent Rare Earth Magnets With Double-Sided Adhesive, Fridge, DIY, Building, Scientific, Craft, And Office Magnets, 1.26 Inch D X 1/8 Inch H by Tutan Hesch

Just a disclaimer so everyone is aware of just how powerful and dangerous these magnets are as I don't think they stressed it enough. If you were to get your finger between two of these magnets as they were coming together you'd at least get a severe pinch/bruise if not possibly break your finger. I didn't injure myself, but I see and respect the power of these magnets well enough to know the danger involved with using them, and unfortunately not everyone does until they get injured.With that said, please know and respect the power that these magnets have and use extreme caution when dealing with them so you don't seriously injure yourself or someone else. Even inside the box insulated with the styrofoam packaging and the adhesive stickers, the entire box will stick to metal. They're THAT strong. I honestly don't know what "practical" household purpose these would serve. If you're looking for a "fridge magnet" don't use these, they'll stick to the fridge but you won't be able to get them off without sliding/prying them and scratching up your fridge. Using them as a "tool holder" as they show in the pictures probably isn't the best idea either, prepare for the tool to go flying out of your hand and onto the magnet from about 6-12" away.Depending on what type of metal the tool is made out of, that "force" could cause the magnet to shatter into a thousand pieces, not to mention the tool could seriously injure someone. Also, don't trust the adhesive stickers, they will rip right off whatever surface you put them on when anything metal gets near the magnet causing the magnet to go flying towards the metal object.If you feel you NEED to use these magnets, I suggest you use them in a safe location, use them to hold whatever you need and LEAVE THEM ALONE. Don't keep putting/removing metal objects on/from them. Also keep away from credit cards, security badges, ID chips, computers, cell phones, laptops. these magnets will wipe the data off of them quite efficiently.Honestly, I'm not going to use these magnets, they are just too dangerous and not safe for the applications (wall tool holder) I had intended on using them for. But that's not the manufacturer's fault. I gave them four stars, took away a star because they REALLY need to have better warnings.
