Tools and Hardware Reviews of Magcraft NSN0601 1/4-Inch by 1/10-Inch Rare Earth Disc Magnets, 50-PackCustomer Review: Fun for all ages Summary: 3 StarsThese should keep kids entertained for hours. The are fun to form into chain and shapes and devise all sorts of experiments with.
There's one huge problem though. They are brittle. It doesn't take much to get a little chip in the outer coating. Once that happens, more and more fragments come off until you have huge chunks missing.
If these had a thin layer of shock absorbing paint or coating of some sort, they would last a lot longer.
No matter how careful you are, they are going to chip eventually. I was pretty impressed with their strength, disappointed with the durability. Oh, well!
