### ⭐⭐⭐⭐⭐ Good value for money

Good quality feels good in the hand and a lot larger than I expected but works extremely well well good grip

### ⭐⭐⭐⭐ Good quality, shame they're imperial.
*by S***T on 30 November 2019*

Good quality, can't be faulted as long as you are OK with imperial sizes. These are clearly a US product. Used in isolation they are fine, but if you need to combine them with other knobs or T nuts that are metric then you're out of luck. It's a real shame you can't get this quality in metric.
