Just thought I'd give my thoughts on this after using it a week or so. It's now available on the 250c and 75c and what a nice vape it is. I have always been a TC vaper. No use for power mode. I've been known to forget to open the JFC on occasion. I also like the consistency. I have been using Replay mode in wattage on my 250c and 75c for a few days now. Wow! This is an excellent vape! Get the same puff time after time but without the steep power ramp down of TC. I vaped a tank completely dry and just got a warning along with no vapor. With wattage alone, I would have gotten a dry hit. Plus, though it's likely due to knowing it is different, the flavor seems to be noticeably better. If Replay can make a wattage vaper out of me, it's sure to be a winner.
