I tried the Blu a year or so ago. I actually LIKED the disposable ones (ducks head), so I bought the rechargeable kit. Boo! That was a depressing and irritating experience--went right back to smoking. While I regret wasting money on it, I look back now and truly regret not researching more at the time. I'm a third-degree black belt in Google-fu, I'm sure if I tried, I would have found y'all back then. Oh well, I'm glad I'm here now, that's for sure.
