Decent, but....
Item Package Quantity: 6, Color: Green
These magnets were decent, but not as strong as I hoped. They are good enough to hold a shovel or helmet, but anything over 10+ pounds did not work.

Good to average purchase but they work.
Item Package Quantity: 10, Color: Green
Magnetic hooks are well made, the hooks have plenty of strength. The magnets on the hooks aren’t quite as stout as they should be, but all in all they were a good buy.

Great holding capacity for hand tools
Item Package Quantity: 6, Color: Orange
I needed to add space to my workshops metal shelves and these are perfect for hanging hand tools around the metal bracing. They have enough holding capacity to hang a small sledgehammer. Now I can readily locate tools and allow for more space on the shelves.
