This is the first thread I've found that even mentions the Inferno, good or bad; actually, I haven't heard anything bad about it yet. I was shopping around for an eGo-type battery, and after going back repeatedly to volcanoecigs.com and hearing only good things about the Inferno and volcano, and comparing prices, I ordered a 650 mah Inferno (battery only) with the usb passthrough feature, and I absolutely love it; It's virtually identical to the eGo-biggest difference is that the Inferno has a push on cone rather than a screw on, but I prefer mine without a cone so it looks cleaner; also I like that they chose to call it 'Inferno' (in keeping with their volcano/fire theme) rather than some variation of 'eGo'; and I couldn't be happier with the performance-better vapor & better flavor than I was getting with stick
batteries, at a reasonable price; of course only time will tell how well it holds up, but it's been my experience that problems will usually show themselves within a day or two of using an electronic device. I really believe I made the right choice.
