Worked well in all weather with only minor performance flaws in near sub temps (winter in Maine). It really improved on the front grip area, anyone with big hands knows what I am saying. I don't really have anything to base performance on before I installed it, I got it the same day and put it on first off. Istalation is quite easy although the instructions that come with it leave a little to be desired
Mine only lasted about a year then the seal around the swivel end blew out, talk about heartbraking! other than that I have nothing bad to say about anything Tippmann does
For the price ( I think I paid 40 bucks for the kit) you can't beat it, like I said, it was a breeze to install (looked really sweet on my spyder too!) I would say this is the best thing for a starter upgrade next to a barrel and drop forward. go for it! I am only giving it a nine though because the darn seal blew out on me right before a game otherwise a 10 would be apropriate.
