In a nutshell, Im a newb who has only really used DCC's xl. Have has some MAJOR BATT isues over it all, wont blame LR Dcc's yet cause apparently the jury is still out on that. I cant blame Riva either cause mine are knockoffs! Flippin out till my epower gets here, trading off my half dying 4 egos, 3 rivas, 2 smoke tips,and about 15 'various stages of 'CRAP' cig-styles . BTW dont EVER buy used cig styles of ANYTHING!!! ThEY are disposable at best. good luck getting a week out of it!! ANYWAY... as I am having to BABY my batts, I had to LOSE the DCC's, drip when possible, and what I ofund interesting... somehow my cartos are doing a MUCH better job at this when pulling out the 'stufff'! explain if u can. Not an atty person, but when having to drip, my 'better' atty gave me a nastier tase about 80% of the time. I know im a newb, but modding a carto, in this instance, I can get a good vape!! I know that there are many variables, Im just glad that I found a way to make it all work till my epower gets here!
