Yeah, information is key when you get into cloud chasing. I got into them because of ease of testing flavors since I DIY. Also it was a good buy as an authentic for $80 vrs $200 one. If and I do mean IF you get into mechanicals, here is some great info from our forum battery guru: E-Cigarette Forum - Baditude - Blogs For Safety is key here. Regulated is a great way for beginners I say. With mine, I have the Subtank from kanger on my regulated and I don't like changing tanks and such all the time so having 2 devices that work with RDAs are good to have. PS I'm a Flavor Junkie so clouds don't do me justice even though I can.
