Great magnets. While I'm not a professional and have no tooling to attest to the accuracy of the data sheet, I strongly recommend them to anyone who needs a small magnet. The magnetic field is very strong, as expected of a neodymium magnet (I'm actually using the leftovers to hang screwdrivers and pliers on a steel bar), and the surface finish is absolutely fantastic - unbelievably smooth, and VERY scratch-resistant - making them the best friend of 3D printers (just don't forget to clean them a bit, because contaminants CAN still mess up your attempts). Though that smoothness and strength can, like most other neodymium magnets, make it a chore to split them apart - I'd recommend using a wedge to pull them apart, because smaller magnets are very easy to lose if they happen to be flung places.
The delivery was much quicker than anticipated as well, and they arrived in perfect condition. The staff are incredibly easy to contact for questions. The price is very competitive, and with that quality of magnet (if the magnet quality carries over to other items), it's a great choice for hobbyist craftspeople, amateur engineers and professionals of all kinds alike.
Overall, I'm definitely coming back here to get more magnets for projects, and you should be too.
Thanks for the great feedback. Just a quick note on separating magnets. Most of the time just sliding them apart will do. The very big & strong ones can be a challenge. Using wood stacked on 2 levels can be a help.
