Work great
Item Package Quantity: 6, Color: Black
Relatively strong hooks. The metal I have them on is thin so the magnets arent as steady as I hoped but thats my fault not the hooks. Ample hook space and solidly built

You need these!
Item Package Quantity: 4, Color: Black
These are not really “industrial strength” but they work great and are decent quality, especially for the price. I bought them to use on a sheet metal barn and they hold halters, rakes and other supplies with ease. Out of curiosity I did toss a dewalt drill in one and it held even though I ordered the medium size and the drill didn’t fit super well.

Very useful tools or helmets hanger.
These are quite useful and hold anything that’s less than 10lb. I think it can hold heavier items but I think it’s best to keep it light and the magnet strong enough to make it very convenient to affix it to any metal cabinet or poles.

Magnet strength is weak AF
Item Package Quantity: 30, Color: Black
Magnet strength is absolutely terrible! I was hoping that they would be strong against my shipping container as the product suggests, but I put a item on it that barely weighs 10 lb and it started sliding down the wall. The magnets are not strong at all!
