It’s a great quality magnet but one of them was broken by peaces when opened box. It was a big disappointing for the money. It never happened before and I hope they should be more careful when packing. I feel frustrated.
These are very powerful magnets for their size, but like all neodymium magnets, they are brittle and prone to breakage. I bought these epoxy coated magnets, thinking they might be more resistant to breakage, but not so. I have already broken two while separating them. My fault for not being more careful, but just be advised that the power of these magnets makes them very prone to snapping back together while separating them, and if that happens, it's pretty much guaranteed that one or both of the colliding magnets will chip, crack, or break into dangerously sharp shards; the epoxy coating does nothing to prevent this.
