Review on Revolutionize Your Precision Repairs With Wowstick SD 23-In-1 MINI Electric Screwdriver: Automatic & Manual Power, LED Lights, And Rechargeable Battery. by Jeffrey Dunn

A toss up between 3 and 4 stars. The motor isn't super strong, so if a screw is snug you will still need to spin it. If you are imagining this thing just ziiiiiiippppp'ing out your screws, that won't be the case. It's relatively slow - this isn't a bad thing for delicate scenarios - and not very strong. The screw needs to be quite moveable before the torque of the driver will turn it.That said, it does turn screws for you. If you have a bunch of un-snug screws that you'd like to screw off at a similar pace as you turning a screwdriver, but without having to turn the screw driver, this will do the trick. I actually rather like the bit holder, unlike many other of the reviewers, though I don't expect it to last a terribly long time on my workbench, as the tube is just thin, cheap plastic.All in all, this thing is definitely worth around twenty-five bucks, and arguably worth the forty that they are charging. Useful, but I could certainly dream of a better tool.
