4Pcs Rubber Coated Magnets, 30LBS Bolt on Magnets with M6 Threaded Studs and Nuts, Strong Flag Neodymium Magnet Mount Base with Rubber Coating Non-Slip, Anti-Scratch for Light Bar and Add Mirrors

I used these to attach my Blink doorbell camera to our Barndominium. This was a great solution to avoid placing screws in the metal.

Very strong magnets. Worked well with what I needed them for

I wanted to mount the surge protector to my desk without having to drill holes, and this completed that objective. The magnet has stayed perfectly in place for over week since installing it. They're also not difficult to remove from the metal.Word of caution, be careful not to get the flat side of one magnet fully on the flat side of another magnet. They are difficult to pull apart this way.

Awesome little magnets encased in rubber so there non marking

Good product. Simple and easy to use

These are awesome. I used magnets to mount a small paper towel holder on fridge.

Excellent quality and strength

The overall design seems well executed, but you should be aware that these are not single, solid magnets and are much weaker than you would expect from their size. The disk is some kind of non-magnetic material covered in rubber, with just 6 small (10mm) disk magnets imbedded in it. They’re only about as strong as a typical refrigerator magnet, not remotely close to a solid neodymium magnet half the diameter.
