Just got my V5 about 20 min ago coming from a V1 then V2. It's exactly the same as the V2 with the body, I think somebody said it has firmer buttons but it's literally the same, which isn't a big deal. Took me a few to figure out the new menu options but basically you set it to watts and then you're good to go. I took out my new AFC then raised the top collar as high as it could go with the AFC to make contact just to be on the safe side of not pushing the pin down. I can't give a great review on it yet (but it seems the same) with vaping but somebody said that the RMS mode is back on the V5???? If that's the case I'm at a loss because I can't find it in the menu or holding down both of the buttons for 10 sec it doesn't switch.
Edit: Figured it out. You hold the left button for 10 sec to switch the mode. Why that function is an option is beyond me but all things are good now and I won't be frying some heads.
Maybe it was age/bat or whatever but I knew that the V2 misfired sometimes. I don't really remember if it started at the start or over time, but testing it out for a while (20 min) no misfires.
I should add that I got it from fairy-gift also. Ordered it on the 10th and got it in MN on the 24th through the $10 USPS option.
