The pricing on this size and shape magnet is very reasonable. In addition the packaging is excellent with plenty of padding (important when dealing with neodymiums).

Dangerously powerful magnets. Two of these in any proximity to one and another is a receipe for an emergency room visit. These things will impact together with such force they will basically explode into little shards with nickel plating shooting out like glass. Your next surprise will be trying to find all the pieces--you won't.

If you do somehow manage to get two of these together without ruining them, good luck ever getting them separated again.

I am an applied physicist working in the area of sea wave electricity generation. I have worked with this magnet, and I consider it the strongest magnet that I would be willing to work with as one person. THEY ARE DANGEROUS. when I work with them, I am nowhere next to electronics, all my credit cards are removed from my person including my electronic key else I will be locked out of my lab. Furthermore, I wear shatter resistant goggles, cloth gloves to prevent the skin from pinching, and never have more than one loose magnet out as I assemble my magnet stacks for my generator. The magnet itself is superb in construction, but it IS NOT FOR CASUAL PLAY.
