Very good upgrade for the Kayfun Lite 2019. Highly recommend also great service from Creme de Vape.

I was really happy with lite 2019, just set and forget but this new deck with the new airflow pin is another level. Easy to use and quiet. I like a tight draw and some .8mm can be too tight and 1mm is too much. This is a fine tune system and the best flavour hands down! Fast shipping and great service as always.

Perfect upgrade, definitely makes my Kayfun lite 2019 flawless, easier to adjust the air control without any leakage from 510 pin
Unlike the old method with the plastic adjuster
very fast shipping and excellnt customer service as always from Keith
