I just got my DSE901 yesterday and it's awesome. I'm a half pack Newport smoker for almost 10 year. Yesterday was the first day I use E cig, all day I only smoked 2 analog, it's greatly reduction. I really enjoy reading the forum and smoking a E cig. I hope the E cig. can help me cut down analog completely. The only thing bugging me about the DSE901 is I have to fill the cartridge so offen, maybe I just vaping too much? Anyway great experience with the DSE901 and great forum.
