CMS Magnetics® Grade N52 Super Strong Neodymium Magnet Ring OD1.26 x ID 1/2" x 3/8" - Rare Earth Magnet Ring for Classroom, Science Project and DIY Applications - One Pack

Strong magnet, be careful with your fingers or there could be a blood blister. It Came packaged in multi-layers of corrugated cardboard which kept it well protected.

Very nice high quality with great holding strength.

I bought two of these magnets and used them stacked on top of each other in a place that would get water splashed on them occasionally. One began to peel and rust after a few months and the other still shows no signs of rust after over a year. They are plenty strong but you've got a 50% chance that they will begin to peel and rust.

I bought this as a retrieval magnet for anything that gets dropped in a drain or under a cabinet. This has got to be the strongest magnet I've ever bought. I have no doubt when they say it will pick up 60lbs+, they mean it. It starts pulling about 1.5" away from a metal surface. Once you hit that threshold, you can't hardly hold it back. Love it

Be careful, extremely hard and brittle, but very strong. Two hitting each other will chip.

Great quality, in regards to magnetic field. The physical magnet itself isn't coated thickly by metallic coating. Small impact of another Magnet will cause chip/bubble/on surface of the Magnet.

My husband used this to replace a magnet in his phone holder in his car. He says it works absolutely great. It holds the phone very securely and he's very happy with it.

Very small
