High quality and build well. Lightweight and easy to use. Can’t beat the price either.

### ⭐⭐⭐⭐⭐ Great tool but had one issue
*by M***C on September 22, 2021*

The exposed area of the bit was not long enough to reach into most of the IEC motor starters, breakers, and contactors that I wanted to tighten. The insulation stops it at the finger safe, prohibited approach boundary just shy of the fastener.
