Did you check the foam air filter on the bottom? I have a number of vapes and my Digit has been languishing but I started recently using it again regularly. My state went med legal in Dec and in a bit of over enthusiasm I bought eighths everywhere of a lot of flower to try and see what I liked in our new market. I should bought grams as I now have some flower that I just wasn't crazy for. Not bad, just not crazy for it. So, in an effort to consume said "not great" flower I broke out my Cano and have been using it thus: .25 - .3 g in an easy valve, temp to 446, put the bag on after a five count from turning on the fan, and fill one completely milky bag that puts me away (I vape for nighttime pain and sedation so getting put away is kind of my thing). I will put a second bag but its wispy....but just to make sure, I do it. Not the most efficient way for flower consumption, but wow does it work and work wonderfully. I get like ten milky hits from that first bag.
