A Joy to Use

It works so well. It is mini engineering at it's finest ...

Strongly Suggested

The motion control is extremely accurate and this screwdriver will probably save your wrists from carpal-tunnel if you are doing A LOT of precision screw-driving!

Five stars

I think it was made for me because I'm very excited about how helpful it's been

Excellent tool for precision work

Excellent tool for precision work. Don't expect enough torque to pull out tight screws, which is actually a good thing for precision work as it prevents accidental stripping. Magnetic tip and speed control based on how much you twist your wrist make for an intuitive and easy tool without giving it a second thought. Unlike cheaper tools, its small diameter makes it work anywhere I use a normal small precision screwdriver.

quick and easy

amazing, this has saved me hours and hours of work bolting together printers
