Recently bought a KR808D1 for my wife along with a pack of their pre-filled cartos. I haven't been satisfied with my LR cartos that I'm filling for my 901. So this morning I tried one of their cartos, smooth flavor, 18mg on my 901. Then tried a 11mg carto that came with the kit, and so far I'm loving the flavor, TH, and vapor. They both seem satisfing to me, and I've been mixing 24mg and 18mg to get a 20mg mix with what I have been using. The 808 cartos blows away what I've been doing, and now I don't know what the difference is. Is it the 808 cartos, the liquid, or a combination of the two? Now I've got to see what their cartos are like when I have to refill one. Thinking I'm gonna have to get some of their juice. Oh, and the wife likes her set-up also, so at the moment We are happy campers.Er, vapors.
