## Customer Reviews

### ⭐⭐⭐⭐⭐ I required these ball bearings to repair a Yaesu KR550 ...
*by B***B on 15 June 2015*

I required these ball bearings to repair a Yaesu KR550 rotator which needed 52 balls.They were the correct size and worked as expected.I hope they don't rust as quickly as the original manufacturers "stainless" ones.

### ⭐ Do not use as paint agitators, they rust.
*by R***E on 28 January 2019*

Bought these as agitators for use in Vallejo paint pots. After about a year I noticed rust marks on the inside of the paint pots.I therefore assume these are not stainless steel and hence are useless as paint agitators.

### ⭐⭐⭐⭐⭐ Good bearings
*by A***R on 26 February 2020*

The bearings were exactly as described.
