Finally got a change to do some hardcore cold vape testing on the Xmax V3 Pro. Around Thanksgiving I took it up to Michigan and thanks to the nice people at the "Nirvana Center" I got some nice Gin Cake and Terpwin Station. It was about 20º at night and I took my dog out for a 10 minute walk and the Xmax V3 performed just fine.
This time I went up to Marquette, and took the XMax v3 out skiing 2 days in a row. The first day it was 30-35 degrees outside. Filled up my V3 in the morning and then filled up 4 Fury 2 dosing capsules for recharging at the summit. Had a great time, refilled the V3 3 times. Was doing on-demand about 380º. Capsules worked like a dream. Yeah you have to turn the heat up a little more to get the same vapor production, but when your on the summit, I doubt you'll notice the difference. This time loaded up with Motorbreath (thanks Cannabis Lupus), this was an outstanding sativa dominant hybrid for skiing, apparently fuel and skiiing go together very well.
But then the next day:
temp dropped it was 15º F. The V3 shut down several time when I tried to use it at the summit and my coat pocket wasn't keeping it warm enough. I till managed to use it, but I just had to restart it several times. Still made it through the first bowl and two more capsules, but the cold eventually got to me and I had to retire a little early. The XMax still did it's job, I thoroughly lifted for every run, but it probably shut down a total of four times over the day.
btw: as for cleaning, maybe once a month I've sprayed 99% ISO up into the screen. Then I'll crank of the heat cover one of the air intakes and blow through the other air intake. Seems to working pretty well for me 3 1/2 months into ownership with pretty frequent use.
