I started using the disposable Vuse pods. I'm 2 weeks into it and found it very useful. I am from South Africa and like everything else in this horrible country, the Vuse disposables costs me R60 (South African Rands) According to my calculations I am saving money on one Pack of sigarettes since switching to the Vuse disposable. I must also confess that I don't get the 500 puffs that the manufacturers claim I'd get. The device has a silicone seal at the bottom where the airflow gets generated and a silicone cap to keep the mouthpiece closed. I think when buying these disposable Vuse pods, keep those silicone plugs in the bottom of the decice, and open it only when you are going to vape. Other than that, keep the silicone seals on so to prevent any leakage onto your clothing. So in summary, I like the disposable ones, but the battery probably dies way before the liquid is depleted, and it is expensive for a thow-away and that my downside.
