Review on 50Pcs Neodymium Magnets With Countersunk Hole And Stainless Screws - Strong Rare Earth Magnets Disc For Locker, Tool Storage, Crafts By MIKEDE by Philip Berry
Cheap, brittle, broken.
These magnets are INSANELY strong BUT there is an issue with them.The outer coating, whatever it is, is thinner than a sheet is paper and does not sufficiently protect the magnets themselves. Rare earth magnets are known to be very brittle and because of this, they are usually coated with a thick enough metal coating to protect them. When I received these, I opened the package, pulled one or two magnets off the stack, and then when they snapped back together (from being just a couple inches apart) there was a visible spark and one of the magnets broke in half. Another was chipped and cracked.For this reason, I can only give these 2 stars. They are extremely strong but not stable enough for their strength.
- it was used to hold my projector screen.perfect and strong
- The magnets may not be suitable for use on painted surfaces
