Hi guys. I bought a Kangertech subvod about 3 weeks ago. The guy who sold it to me primed the coil for me and I was enjoying it for the first 2 weeks then I got that burned taste with my Vaporised Eliquid. I did a lot of googling, and watching You Tube clips then tried replacing the coil. This failed so I tried again, still the same horrid taste that reminds me of really cheap cigarettes. The online advice often seems contradictory regarding how much juice to put on the coil. Any thing I could try before I take it back to get it replaced or refunded?
