well my girlfriend and I as well as couple of our friends want to get into this e-smoking thing and away from all the tobacco stuff as its not good for you and its getting damn expensive putting away money for those sticks. I did a bit of research and it seems that the dse901 is the way to go for all of us. But I have a couple of questions, firstly where is the cheapest place I can get the 901 in the states? and how much liquid or cartridges can you smoke before you have to replace the atomizer? Also how is the battery life in general? I know battery life depends on use but would I need to charge it every night and keep an extra just in case? Any recommendations to other products or general advice is welcome. I will have other questions soon as my friends and my girlfriend are very interested in this. and also, really friendly community you guys have here!
