High quality imports
Very smooth spinning. Much better than the cheap ones I bought locally. Will purchase again.

Packaging needs improvement
Bearings are fine but some arrived loose in the bag. Better individual packaging needed to prevent damage.

Good value assortment
Most sizes worked great. One size was a bit tight but loosened up after use. Good price for the quantity.
