This is the best pump is ever used!!! At first I wondered what all the hype was about so I decided to go and buy one.... what can I say apart from, its just the best pump gun you can buy. I my gun for the whole day at my local paintball site, it never even broke a ball, leaked gas, mis-fired due to my double cocking. I just couldn't no matter how hard I tryed, fault it during play.
As the others say, it is a little tricky to adjust the velocity at first but once you've got it setup its great. The only thing that could effect my balls was the wind. Very expensive though, but you get what you pay for.
Brilliant paintball marker definately THE one to look at if you are going to purchase a pump gun. A good beginners marker if your not planing on upgrading for a long while, and your not to rough with it. As aswell the other man said it can't get 10 becuase of its price but if it were a bit cheaper I would. Awsome gun :)
