I recently purchased the eGO ONE mega sub ohm tank. I put in the new coil filled the tank with liquid and started to vape. Everything worked great for the first few days but then I started getting a burnt taste every few hits. The coils only a few days old, and I only have my IPV 3 turned up to 30watts. I bought a new coil for it and I am still having this problem. What should I do? I also have an arctic sub ohm tank which works great, the woman at the vape store told me the MEGA was better though... should I just stick with the arctic or is there something I can do to fix the MEGA./
