I have been vaping with a KR808 for a couple of weeks now (my first time vaping purchase) and have recently purchased a Joye eGo w/510 atomizer to try out. My question is this: Why do I get a more favorable vape when I use the KR808? With my eGo, I have tried using cartos, direct dripping, and filling carts for use with the atomizer; however, the result is still a real lack of flavor, but with great vapor! Also, I've been using a 50/50 mix and a 70/30 mix.
