So I picked this up about five months ago. I wanted something to get into tight places on units I'm testing. A Lot of the components are installed with the unit half assembled then Ill have to figure out how to get into them when I find problems on the unit in my test station. Things like high and low gas pressure switches on gas furnaces installed within two inches of the top of the cabinet.
Long story short I have found this to be my tool of choice for most anything I run across. With a decent assortment of 3" or 6" bits I find it to be much easier on my wrist then standard screwdrivers/nutdrivers while allowing better torque. Just passing along what I find to be a very useful tool.
