I have had one and shot it at 10m, its awful mate, you end up not knowing if those loose shots were you or the gun, the power is very inconsistant and on mine it could vary by 50fps per shot!

After i got my LP10 i realised that the gun was crap and i wasn't too bad after all

A better bet for you would be to start with a Gamo or FAS as they seem to be more consistant.
