I will never buy buy an IR air ratchet,junk!THE IR 109XP is a piece of junk.I only trust Snap On's 3/8" drive air ratchets which will take your hand off if not careful and more powerful.Plus they are rebuildable getting them back in a couple weeks just like new.Have a couple 1/4" IR air ratchets that stay in the toolbox,were good and gone wimpy losing power right away.IR makes the best impact wrenches.
