Thanks for the feedback.
After testing this tool a bit more I think it's still worthy of consideration, although it does take some getting used to and might be one of the more specialized drivers I own.
For driving fasteners into wood I think I prefer a pistol grip driver, although this seems to have enough power for soft wood / shorter fasteners.
This tool appears more for suited machine screws and pre-drilled fasteners, like assembly work. With the gyro function I do like the straight handle, it seems like it would be awkward to be twisting a pistol grip around.
Anyway, for some of the suggested applications like interior trim work, outlet covers and the like I can imagine this driver having advantages. Whether it's more convenient than traditional small drivers I'm not sure.
I definitely liked my little 4v Ryobi Tek4 driver for light duty work. After I gave this driver to my dad (he needed something like this), I switched over to a Milwaukee 12v screwdriver for this type of work and it's fine, although a little bulky. I was considering the Milwaukee 4v driver but that is a little pricey for my needs.
Anyway, for $40 I will probably hang onto this tool and see how it goes. I may have to pick up another Ryobi tek4, that little driver was nice for light duty work!
Thanks again for the replies!
