Well, now I'm really disappointed. I made that video this afternoon at 10pm forum time. The battery was freshly charged. It discharged at about 1am forum time. So I got the other one and it has now discharged at 4h00am forum. So about 3hrs smoking time. Granted, I have been smoking pretty much non-stop, and the fact the the atomizer is kinda weak, I'm probably using up the batteries even faster. The Njoy battery is still going strong, that's what I'm smoking now.Now I'm wondering if I should not just return the thing and get a refund instead of asking for a new atomizer. Any opinions? I can buy 2 Njoys for the price of the KISS, but to be honest I would of preferred the KISS to be superior. Very disappointing. Guess you guys were right, sounded too good to be true. I'm not sure what I will do.
