I love this electric screwdriver, Wesco held nothing back when they made this. There are 12 different bits, 2 cartridges that each hold 6 bits which make switching bits super easy. I have 2 boys, they're 10 & 14, they love using this Cordless Electric Screwdriver by Wesco. They think it's cool because it cocks like a gun. I absolutely recommend this Wesco Cordless Electric Screwdriver.
