just wondering if there are any herbal aire 2.1 owners in here? If so have you modded your set up. Or do you just use the factory pump and bags. Personally I'm patient enough to wait for the slow but more efficient vapor bags that I've made myself. Factory bags are kinda lousy. Anyways there seems to be a lot of extreme fans in here and I know there are a lot of happy herbie owners out there. I like the extreme but its nowhere near as durable or efficient (if use 2fan and up) portable as the herbal aire.
