It's not true that G10's don't last, had mine for 12 years before I sold it and it's still in great condition. Come on for a £20 plinker it's not that bad!

Of course almost all other air pistols are better than it, but not in its price range - as a £20 can basher it works fine IMHO. I really don't think you will be disappointed, as long as you remember that it's only £20 and don't set your expectations high :P
