My Dad has one, and i've had regular use out of it. Cracking gun, never had any problems with it. I've had crows, pigeon, maggies, rabbits and one fat arsed rat with it! I find it accurate and not to heavy. The air lasts a while as well. What i would say to you though, is that it loses power when just under 3/4 empty. the shots are meant to be metered, so it shouldn't do this. My younger Brother has the single shot s200 and it does the same, so i would refill the air when it is just over 1/2 empty.
