Thanks so much for your info - will go to their site now and check - by the way, can you or someone tell me about replacing atomizers? I really don't understand what they mean about replacing them once a month, do you order them separate or are they available for all e-cigarette brands? Also, I do not want the liquid replacements, I like the cartridges, is that also available with all e-cigarette brands. Going to check out the DSE Penstyle and see what is there, thanks so much
