I've got the same AB on the left as well, and my compressor is pretty much the same, though mine doesn't have the pressure regulator. I'm on my second AB now, but that was more due to not maintaining the first properly. Make sure to clean it out thoroughly after use and I'm sure you'll have no problems with it. Another good thing is that spares are readily avaialble from here
, which is ideal for replacing nozzles and needles when they've had it.
As for the compressor, mine has a tendency to spurt water out if used for extended periods as the compressor warms up. This is probably due to it being so cold in my workshop and condensation building up in the airline, but thought I'd point it out.
