Review on Wiha 28792 Insulated Torque Screwdriver by Bob Vulpes

Torque adjustment is very good. The color is bright and easy to see. I agree with another reviewer that a square slot and slotted bit would be nice for getting the torque on older screws. It comes with a square bat. My problem is that the bit holder doesn't stay in the grip when you look down. You can lock the bit in the holder, but if you want to unlock the bit, pull the holder out of the handle. I think some lubrication inside the handle is necessary, but it means I have to be very careful when working outside when it's dusty and windy. Not sure if it's easy to clean if it gets dirty on the handle.
