Will Herb, does not seem you will even make three months waiting for reliability data about the CNA30 clones.I have been reading the feedback on the FT site and some on here who have commented about it , it's definitely positive from the reviews i have read, some have said they received one with the same quirks as the Clouper model but overall satisfaction is high .
I have also been checking the feedback for the chips and those are also getting solid reviews. What i am interested in right now is the box mod being offered as a pre order by the makers of the seven twenty two mod , that one comes with a 12 month warranty, good documentation and you can opt for a 50 watt SX chip for under $100.00.
BTW - Five weeks and going well. The device was paid for in the first ten days with my former cigarette money, if I had been still smoking the cash simply would have ended up going up in smoke. I hope you eventually find something that fits your requirements.
