Awesome -- they work perfectly
Style: Updated 3.46in Magnet L Red Hooks 2PCS
Got these to store a DeWalt cordless drill and impact driver on the side of a Gladiator garage cabinet -- and they work perfectly for that. The magnet is incredibly strong, easily supporting the bare tools, and seems even to work perfectly well with an 8ah XR battery on the tool -- not that it's necessary since I don't store them like that. I like that the magnet is padded with rubber. Very nice units, I will get more for sure to store other items.

Incredibly strong magnets and thick, robust hooks. Excellent combination!
Style: Updated 3.46in Magnet L Red Hooks 2PCS
These magnetic hooks are really strong. Seriously! Each part is made to carry weight and last. The hooks are built out of thick steel stock. They bolt up to large magnets that grab onto steel surfaces and won't let go. The cabinets in my shop are all steel so these worked perfectly on the sides of the lower units. I have a few #12 AWG extension cords that are bulky and heavy. Truthfully, I didn't think these hooks would handle them. They do without any issue. Another application is a 30' long #10/4 AWG SO cable that powers my powder coating oven. It's usually unplugged and wrapped up. It would often end up on the floor where it was constantly in the way. The outside of the oven is all steel but I didn't want to make holes in it for cable hangers. Again, I didn't think that these magnetic hooks could possibly be strong enough to handle the weight of that cable but they do. And once they're attached, it takes a lot of effort to remove them! Amazing performance!! I'm thrilled with these magnetic hooks. They are super strong and, obviously, simple to use. Importantly, they stay in place as they should. I wholeheartedly recommend these hooks to anyone. Great product! Incredibly strong magnets and thick, robust hooks. Excellent combination!

Great for the storm shelter!
Style: Updated 3.46in Magnet L Red Hooks 2PCS, Style: Updated 3.46in Magnet L Red Hooks 2PCS
In our storm shelter we had some lights that we tried to hang up, multiple times, with no luck! Then I found these garage hooks. They are overkill for the lights, but I’m so happy that we now have lighting in the storm shelter. I could think of so many other uses for these. They strength of the magnets is awesome!

Magnet is super strong but hooks are not adjustable
Style: Updated 3.46in Magnet L Red Hooks 2PCS, Style: Updated 3.46in Magnet L Red Hooks 2PCS
I ordered this set of Mutuactor magnetic hooks because I was tired of thinking I had things organized and then finding previously hung magnets have slid down the wall. It was a first for me to have to assemble a magnetic hook. This was made slightly more difficult by requiring a wrench. So many items these days arrive with a disposable little hex wrench or whatever is needed for assembly. Not in this case. Maybe the manufacturer assumes if you are spending $15 per magnet to hang your tools you have a wrench handy. Anyway, I got my wrench and found no instructions. I know from life that the order is bolt-washer-lock washer-nut. The next question arose when I found one bolt and several holes... hmmmm. It looks like they wanted to provide the option to screw the hooks directly to the wall. I am not sure the average person would pay that price just for a hook, though. I chose a hole and it seems to be the right one. The good news is I was quickly in business. Soon one magnet was snatched by my husband for his rolling tool cart. He hung his (very heavy) Sawzall and the magnet never moved. He liked the rubber coating that protects his tools. I chose to take advantage of the amazing grip of this thing to hang my most used (and also very heavy) all-clad pan from the side of my fridge. The refrigerator had some sort of glossy powder coat and magnets hold well if you try to pull them straight off but end up sliding down anyway. This is where I came to appreciate the rubber shoe of this magnet. It protects my fridge but I think it plays an essential part in the grip strength of the magnet. I can not slide it around - I need to use two hands to pull it off then place it in another position. To give a magnet strength example I had one magnetic hook on my desk as I was writing this review. My nearby desk-size scotch tape dispenser came sliding over and the magnet grabbed it. I was able to lift the tape dispense just by the magnet grabbing the little piece of metal serrated teeth that cut the tape. There is no other metal in my dispenser. That's it! In summary, four stars because it REALLY grips and holds a lot of weight. Minus a star because I do think they are a little expensive, they required assembly without tools or instructions, and the hooks themselves are not adjustable. I have some similar magnetic hooks and you can move the two prongs apart or together depending on what your tool size is. These prongs are strong and firm and are not moving and this cuts down of the number of uses a little bit.
