I hope you have better luck with your Phoenix's than I did . Used the coil it came with . When it got gunked up , i tried to make a new coil and wick . 6 trys later , and still a no go , my Provari says all are low . I even tried a premade wick and coil . It measured 2.2 ohms on volt meter . install on Phoenix , and yep , too low for Provari to read . Now just so You won't think I'm totally a noob here . I have been building wicks and atty's for over a year now , with great sucess . I have an Iatty , a penelope , a GTUS , and a line , as well as several Vivi-Novas . Only the phoenix has let me down . As far as I'm concerned , it's a piece of junk .
