Too bad the Standard Screw Driver attachement only comes in Metric as it was made in China.

If all you work on is computers or toy robots this could work for you.The smooth edges will still hurt your fragile nerd skin so wear gloves compwiz and casecutter.

The quality on the hand driver is bound to be really poor like most of the cheap all plastic type, poor tolerances and cast potmetal ratchet mechanism with a flimsy blade spring and plastic switch.

Otherwise the price for the bits is way too high, you can get sets from Home Depot, Lowes, etc. on sale for less and they have more pieces. Then add a standard fixed 1/4" bit driver with a magnetic end, and a 1/4" ratchet with 1/4" socket to get into tight areas.
