Bought one of these today and glued it to the wall to hold my MagSafe Apple wallet above my keys.
Pretty damn strong magnets, was genuinely surprised for the brand. Tested it as a stand before gluing it to the wall and it worked rather well, but I don’t have a need for that.

Would it work for a security door
