Back in June, I bought the Joytech Evic Primo 2.0 from gearbest.com the kit came with the Aries tank. I started using it on the 26th of June with the proC1 coil. I change out with an ELEAF iJust 2 RTA normally about halfway through the day and average around 250 puffs a day (I love and hate the puff counter). In the Aries tank I keep Galaxy 50/50 18 by Central Vapers and have not changed what I vape in that tank since I got it, and I run it at 55w I am trying to give as much info as I can so please stick with me, just a bit longer the point is coming. I have had the same coil in since I started using it until the 17th of this month, I changed it because I wanted to try the C4 coil that came with the kit. However, the first coil did not ever give me a burnt taste when I looked at the coil it looked fine maybe a little gunky like if I cleaned it would be good as new. Is this normal for this coil? I mean I have read that you should change your coil every 1-2 weeks and I know with the iJust I have to. Did I just get really lucky and maybe find a magic coil?
