I am Leglessshane, I was born without my legs hence the name. I started the terrible habit of smoking at age 18 and smoked for 9 years, I quit October 7 of this year! Overall vaping has been amazing! But, of course all of us run into issues. So, here goes my story. I have been vaping with my Protank 2 and a eGo-C Twist and doing about 3.9 volt with a 2.2 ohm coil for about a month or two. I have been vaping at 3.9 volts because of the hit, it's very satisfying. Anything lower just feels very "airish" and I'm not getting a great hit. I have had quite a few problems, my latest issue was a horrid burnt taste and turning the liquid a tar looking black.. I went to google and I found that rinsing out the wick and coil in warm water would solve my problem. It has been working for the last two days but I can't vape on the 3.9 volt anymore. It tastes BURNT! I am hoping to upgrade to a Vamo V5 or something in the same price point. I am still doing research on what I want. So, any help or advice would be greatful!
