Nice but could be better ...

This is a well made tool with a quality feel.
But .... The one I have does not tighten as well as its specifications suggest it should, specs say up to 250ft/lbs... Mine won't tighten to 140ft/lbs...
Maybe it's my air supply? ... I have a 14cfm compressor ....
So maybe not ?
Also it has variable speed/torque settings ... Well it does run at three different speeds and the torque settings are different, but there's no indication of what range of values it's likely or capable of achieving within each setting, other than the vague claimed up to 250ft/lbssuggestion in the specifications..
So would I recommend it?
It's small light and well made.. But it's not doing what I thought it would, so on balance no I don't think I would.
