I got this one days before ProVape closed, when new it threw a couple of error codes, then it worked just fine without a glitch until today. I'll use it around the house but won't be trusting it for a while for out and about use.I had it happen with one of mine. Switched out to a back up. The glitchy one works fine. Just giving it a rest. Sometimes they just need a good cleaning and a little DeoxIT.
