I'v been running my PTW since 2007,yes I'v had alittle work on it. BUT I'v used it in the rain with no issues,I always take my G&P for a back up and it never gets used! I still have my ICS,G&P and sold my Classic Army M4 and picked up a MP5. Point is my PTW is by far the best in performance and lack of issues,but I still like to keep the other AEG's around because I like them. It's not that I fear my PTW will go down, and if someone else need's a gun at a game than I have one for them to use

As for falling on a PTW, I'v fallen on mine twice and it's still going! Never broke anything,can't say the same for my ICS as a few small tab's broke on the S.I.R. unit.
All my AEG's run with minimal issues,because I maintain them! Back in the day when I built my ICS it ran me $2200.00 to get that set up. I won't get into what I spent on my PTW (I could have bought a car),but it's only because I wanted all Real steel parts. Not because I had too,but because I wanted too,there's a difference!
