I have been using the Triton for a couple of months now and have not had any issues until now. I am getting dry hits on my purple tanks. I have replaced the coils many times and with in the last 2 weeks, it seems like I am getting a lot of dry hits. I will unscrew the tip on them and then it will vape like new for a few hits then I will get dry hits again. My pink tanks which I have had the same amount of time and used the same amount of time are not doing this. Like I said I have replaced the coil several times and even with a new coil it's doing this. Anyone have any ideas as to why. Thanks in advance for any advice.
