Got the Zeus today and spent the night with it at work. Pretty amazing. I like the dual mode. I haven't used an auto in a couple of years and it was a nice change. I didn't really need to charge it at all but I wanted to try the pass-thru option. Works great. It's almost as much vapor as smoke from a regular cigarette and I haven't had one of those in almost 4 years. If I had one complaint it would be a longer cord. Not a problem where I take my breaks at work, but anywhere else may be an issue. Not that big a deal i'll get a 3 ft extension cord. This is a good bit of kit though and i'm pretty sure i'll snag another one next month. Good Job
