I hope it performs well, but I really want longevity. I am kinda cheap (not too bad or I would not own a reo) so I need something cheaper than cartos. most people get a week from their cartos, I'll be lucky to get 3 days before the nasty taste forms. I am not burning them, but bobas bounty just gunks them up and they start tasting awful and the filler turns black when wet. I dissasembled one of my cartos after 3 days use to find that the coil was covered in soot. the filler was brown, but not black, but the little sock inside had turned black with soot. I am hoping the atomizers will relieve me of this, and that I can clean them with a little vodka if the problem persists.
