## Customer Reviews

### ⭐⭐⭐⭐⭐ Bye again shop
*by R***C on 27 August 2025*

Valued seller, quality goods

### ⭐⭐⭐⭐ Good for toys and other cheap projects.
*by D***N on 18 February 2025*

Great value for the money, used them in 3D printed toys.

### ⭐⭐⭐⭐⭐ nice bearing, low price
*by G***N on 11 January 2025*

I'm using these as rollers in telescope focusers, and they seem to work well. Perhaps not as precision made as similar products costing ten times as much, but with six bearings per focuser and a saving of £2 per bearing, I'm fine with that. I haven't tried spinning them at 30,000 rpm, and don't intend to.
