Great magnets and sturdy hooks
These are great hooks! I needed something quick and easy to move around - these fit the job perfectly. The magnets are strong enough to securely hold the ropes and cables I needed to hang, and yet we can move them around as needed. Great purchase!

Awesome
I have so many of these attached to my tool box. I hang so many different things from them including my drills.
Love them and will probably buy more soon.
Well made and very strong magnets.
