Great Magnets!
I love that these are super strong and hold a lot of weight without budging. I bought them because I wanted to add a pull handle to my metal workshop cabinet. I didn't want to drill a hole in it because I inherited it from my dad. It looks great - like it's always been there (see pics). Since I had a set of them, I discovered that they were even better for hanging my hacksaws and miter saw than the magnet hooks that I had been using. The round knob holds them more securely. This was a great find!

Basically works well enough
It's magnet. Reasonably strong for this small size ( aprox 1"diameter) . Bigger sizes available - use as needed. Product info on Amazon listing was reasonable - notes 40% loss of (weight) strength if on painted metal surface, etc. Packaging mediocre. Cardboard covers (discardable) not attached upon arrival. No product info on box. If you don't like them, then either return immediately or you'll be stuck.

Mehhhhhh
These are just ok, I'm actually a little disappointed because I thought I had found the perfect coat hanger. Out of the package I was disappointed when I stuck them to the side of the frig - which is textured - and they slid right down. Then I put it on the side of the clothes dryer and I really had to tug to get it off, ok, now I'm happier. Brought them to work to use as a coat hanger on the side of a metal file cabinet. They stick quite well. Do they hold 16 pounds - no way, not even close. My coat is maybe 5 pounds and it slid right down the cabinet. My solution for now is to stick it to the top of the cabinet and hang the coats from there and it seems to stay. Should obviously not be that way. The only reason it even got three stars is because it does seem to be well built and good quality. Clearly though the magnets are not that strong.

Strong
I ordered these for flattening the back of the irons (Blades) for my hand planes. A pair of these stuck to the iron make great handles for lapping the iron on a piece of sandpaper. They hold well enough that they don't come off or slide around and yet they are still easy enough to remove them when needed.

Having a good sized handle/knob helps with easy liftting off metal surfaces. Love this magnet at home and work.

J'en utilise un pour tenir un torchon à vaisselle et cet aimant est assez solide pour adhérer à la paroi du réfrigérateur, ainsi le linge ne tombe pas par terre. Cette méthode est meilleure que de placer le linge sur une porte d'armoire. Je commanderai peut-être, plus tard, d'autres de ces aimants. J'en utilise deux autres pour maintenir en place le rideau de douche décoratif, quand il est fermé.

Funcionan muy bien, tal como esperaba

Son excelentes imanes. Sumamente prácticos, los utilizo para sostener papel, tela y algunos otros metales. Sin duda son los mejores con esa agarradera.
