You are going to think I'm nuts but I think my atomizers are getting spoiled. Not like ruined, but like a toddler who doesn't get their way. I made the ".08 cent" passthrough for my cigar. (BTW big thanks to INVIDREGIS for a 10 min lifesaver...good job) It worked like a charm, and it seems that they last longer on my usb power than batteries. But when I take them off usb power and put a battery in they were soooo sluggish. I put them back on usb and they are great.(tried 4 different fresh charged batts) I thought it might just be me being used to the better preformance and not the atomizer so I compared a cigar that has used only batteries with one that has been on a passthrough and there is a big difference. The cigar that has only been on batteries works better than the one that has been on a usb. Granted this is a small sampling I only have 2 that prefer the usb, but is this possible? If I'm not crazy, or at least that isn't the reason for the problem, is there anything to do other than keep a dedicated usb cigar? also can anyone explain this? All openions welcome, thanks.
