Its a great gun. I never had any kind of problems with ball breaks, as my friend have. I guess it needs some grinding ,, and the macro line has blown away, so I went to a store and got a new connecting device for the buttomline. Alright, no clue what the rest of you are talking about. Ever since I got this gun, I have smacked around other Spyders, Tippmans, Automags, and a Core Sharc.
Body scratches really easy, but that's kinda superficial.
And I would say after a while you should change the bottomline on it, it is only plastic. But you shouldn't need to do that for a while. Other than that, nothing. For the money, this gun is well worth it. Word to the wise, don't but the Shutter, it is a piece of garbage that doesn't work well.
