My JB had a broken switch after two weeks of use so I sent it back for repairs. Got a brand new one back in the mail today and its working great. Only one problem it had a little juice left in it from Carlos testing it out I assume. I took a big draw off of it and it shocked me. I have always been a zero nic guy from day one. That nicotine went straight to the head. Wow I haven't had nicotine in my body since May 09. Damn Carlos I'm not sure what mg nic you vape but I just can't handle that. Thanks again for the great innovation on your part and keep up the great work.
