Work's as it should. thanks

### ⭐⭐⭐⭐⭐ Great tool
*by G***L on 9 December 2022*

Simple & easy to use, a little worried about the longevity of the switch as it feels a little flimsy but working well so far.

### ⭐⭐⭐⭐ Good for this price
*by L***  on 7 October 2024*

It could be better if it made it in a good solid plastic. Other wise it's works good
