first of all... i saw your review and immediately got one on order. This would come in handy for a lot of my jobs i do where im staying in a spot for a while. but when im on the move, I use the Bosch SBID9 multi-purpose bit set that comes with a small tool belt pouch. In my line of work i use a lot of different size nut drivers, philips, square, and extensions. this little guy is perfect for that.
