This air ratchet is a very good buy when purchased with a 20% off coupon. It has ample power for use where a small fastener is used. It is speedy enough to make quick work of a series of fasteners. The socket retainer is a little weak, but still holds the socket ok. Air consumption is low enough to use on a home compressor. The first one I picked up in the store had a defective trigger mechanism, so I checked them all and found one that was smooth. For the kind of use that a 1/4" ratchet gets it is a bargain.
