I dont know how anybody can find any of the o rings on the Troll too tight. The o rings on the deck are not protruding enough to create a good seal with the air flow cap. I can pull the top cap out without any pressure at all and the inside of the top cap gets wayyy too much condensation on it. I cant even screw the thing in my mod completely without the middle piece spinning. I have to screw in the deck first and get juice all over ny fingers. Everything else is OK but honestly my doge is much cleaner to use and just as good a vape. Its also not HUGE like the Troll. Come to think of it I really kind of dislike everything about the Troll except the nice deep deck and ease of building on it.
