Ahhrrrhgg! Now that I got that out of my system I'll explain. I started out on an evod w a td3 on old coils which burnt up in less than a tank of 2.2 ml. After going through about 8 coils in 2 weeks I bought a mini protank3 and same issues, only lasting up to 3 days tops. So I bought an itaste vv 3.0 and gave away my evod battery and td3. And began using new coils, light colored juice @ 80 pg. so I'm thinking maybe just a vender with bad coils? Finally another shop opens. I am in country land not much available. He talks me into buying a spinner 2 clone. I got 3 coils from him in 4 days and just about to give up! So he says buy the nautilus u can chain vape & coils will last you a month! Shows me all about it, priming etc. the next day it's burnt as heck. He said he thinks he gave me a bad battery and replaces it. Got thru 5 ml. On this coil... A record for me and burnt again on bvc coils! Please help am I doing something wrong? What should I buy and where online? Is rock bottom vapes good??
