  • Nice quality and variety
Size: M2/2.5/3/3.5/4/4.5/5/5.5/6/7/8/9/10-840Pcs
It's a nice set. I only needed one size for now but will definitely be able to use the others. Not sure what I'll do with the smallest and most plentiful size but it's all good. The set is nice quality.

  • Missing bearings
Size: M2/2.5/3/3.5/4/4.5/5/5.5/6/7/8/9/10-840Pcs
The bearings themselves seemed fine. Only issue was my container came cracked and I was missing a ton the bearings. (At least a few hundred) They weren't in the shipping container either.
