Review on Power Up Your Projects With MIKEDE Cube Neodymium Magnets - Super Strong Rare Earth Magnets For Science And DIY by Anthony Lanka

Super powerful and very well made. Mine came with no flaws at all. I've always wanted one this big and powerful and am very happy to have one to play with. Don't worry, I'm an adult and do play with magnets in a safe manner. Although I would not get this for a child, I can highly recommend it for an adult. I've also used it to pull bits of metal like screws and nails out of the ground around my house, and used it to find studs in my wall; it certainly has tons of uses.
