I had to swap out my broken older Kobalt Air wrench, and it seems that they have upgraded the line. I opted to pay a little extra and get this new 1000 FT/LB beast. needless to say, its a powerhouse that won't blow out your ears like IR-231's do.
My little 3/8th air gun died when it fell off my new lift the other day. I went to swap it out, and found out that they had discontinued the older model with this new one. WOW! Night and day performance out of this lightweight unit. Much much more powerful than expected and very nicely built.
