I personally love my bliss, I mean LOVE it! I run a single coil on it, but it's nice to have the option to run two if I want, or u-shaped wicks. The only two things I don't like about it, the tank is only about 2ml, and it's heavy. I'm pretty sure the tank actually holds more than 2 ml, because I vape pretty heavy and it lasts through an 8 hr shift and into the evening quite a while. It's heavy too, because it's built really well, but with food grade stainless steel instead of titanium. elitevaporworks has a titanium version coming out, but it's going to be more expensive. I picked up my bliss in the classifieds for 120. The things I like about it are the tank protector, the dual airholes, and phillips head screws instead of allens, much easier to work with.
