Pros:
Highly recommend this air ratchet, for 3/8" drive rated at 100ft pounds it is more powerful than any 1/2" I have used and is comfortable to hold. I especially like the sealed head design that keeps dirt and debris out of the gears, and it even has a 360 degree adjustable exhaust. This model was discontinued at HF, but if you find one buy it !

Cons:
None really, although some might say it's loud, just wear ear plugs.

Note: It does require a good amount of CFM to operate best, high flow couplers and minimum air restriction is recommended.
