I have had my lux for several days now... First of all, I love love love how it looks and feels in my hand. It seems like it's really solid and well made, which is what I've come to expect from Modern Vapor. The charge length surpasses what I have with my riva and ego, I think they are around 650 mah. The riva is higher but I can't remember.. and I'm not gonna look it up right now. 7?? maybe? Anyway, I've had a cold, so all my flavors taste "off" so I imagine my experience will improve greatly once I'm past that. I first used the lux battery and cone with the 510 atomizer I'd been using. I found that it worked well on one battery and didn't seem to be making a connection on the other one. Then starting yesterday I decided to attach the 902 (regular atty, not the SS that also came with the kit). I can't say how it's going though because my taste and inhale capacity are seriously under par with this cold. I'll get back to you. But so far, I am super happy with my purchase and I feel it was worth the wait and the money.
