Don't buy the Winchester set from Brownell's. The day it arrived, I put a bit in and removed it, out comes the magnet from the driver. Ok so driver is junk, no biggie. I'll just use my Craftsman, fits in the case and all. Then the smaller bits one by on started to bend. I was using the correct size. Ok I say it wasn't that much money. When the 1/4 inch slotted tip snapped I was really not a happy camper. So from purchase date to ruin was about a month. Junk, Junk, Junk.
I would bet that all the "Big Name" companies sets are the same. Chinese junk. I have some old wood handled screw drivers, unknown maker, that my dad gave me that I have used on pretty much everything in my house and garage that are bulletproof (pun intended). Thats what I'm looking for. Good post. I will be looking for some of the brands mentioned here.
