I am going to assume here, that my complaints are with the cartos. This weekend I had everything just right on my 808, and 901. For me the TH, flavor, and vapor were perfect. Man I was in heaven. So for about 3 days I was enjoying it, then this morning I thought I'll clean the two cartos and put on fresh ones. I guess that was a mistake. My 808 is about half the TH, and vapor I was getting, and the 901, Th is good, but not much vapor. So I put on another new carto on the 808, and the vapor is good, but no TH. Man, I can't afford to buy a ton of cartos and go thru a bunch each day to find a satisfactory one, nor do I have the time necessary to do this. The only difference in the equation is the cartos. How do you all do with this. Am I the only one that is having a helluva time with this? Thanks, I would appreciate your comments.
