Review on Mavoro Strong Magnetic Hooks For Hanging. Up To 65 Lbs. Set Of 2 Black Magnet Hooks Heavy Duty Magnets, Neodymium 52 Rare Earth Magnets. Rotating Swivel Style Magnet Hook For Refrigerator, Locker Etc by Nathan Tank

The design of these hooks is very nice. They look good. I purchased them to hang a very lightweight canvas picture on top of a magnetic black board in a classroom. The picture weighs less than four pounds, and these hooks are "rated" to hold 65. No way. I had to use BOTH hooks to hang this lightweight picture since the hook alone slid down the surface to the bottom. Perhaps it's the chalkboard surface, but I have a super strong magnetic hook on another picture adhering to the same surface and it doesn't have this issue. With both hooks attached, it did the trick, but I would have preferred it if it only took one hook to hold such a light item.
