Hi, I'm new to this forum. I got my 1st vape pen last week (precursor to the G5) at the Doc's when renewing my card. At first it was great, although sometimes combusted the flowers, but now only 1/2 of the coil glows red. Is there a fix for this? Thanks!Edit: after messing with it, preheating the chamber for a full cycle instead of 2 seconds gives a nice hit, and you can hit it 2-3 times . It doesn't combust like it did initially when the whole coil got red. Was thinking about returning it, but I think I'll keep it now. Sent from my iPhone using Tapatalk
