The Autidefy Magnetic hook 12-pack is ok. The hooks are supposed to hold 12 pounds, and I tried to hang a pair of lightweight cotton coveralls from them multiple times and it just slides down my magnetic door. The hooks themselves turn really easily which is very inconvenient. They also have a strange chemical odor; which I found repulsive. These hooks work fine on light things but otherwise don’t work very well. I went back to amazon to verify their information and things about them but unfortunately the listing no longer exists and I continually get an error code when trying to find them. They definitely were not worth the money I paid for them since they can’t actually hand the 12 lbs I was led to believe they would hold. I think if you know they are for light weight items they may be worth getting if you need a small magnetic hook. I otherwise have no idea what to do with them since they don’t work for the purpose, I bought them for.
All in all, these hooks work fine for light items and definitely can’t handle more than a couple of pounds; especially not 12. If you need them for light weight items, I would recommend them.
