Had $10 free reward points, so I bought one ball grip screwdriver and also a 1/4 long shank square (robertson) bit. It fits perfectly in it the ball screwdriver. These are made in Japan, but only the packaging says that (not actually anywhere on the screwdriver handler or reversible bit).
I'm a huge fan of the Wiha (German) screwdriver soft finish handles. These aren't quite the same, but equally as comfortable I'd say. Nice thin portion for the fingers, and the thick ball at the top to fit into your palm.
The two in one PH1 and PH3 freaks me out a bit. I suppose I'll see how it works with time.
