I started vaping the end of February and the wife gave me two weeks to see if it worked and had me pick her up a vv V3 (same as I had). Neither of us has had a smoke since. She has vaped the same menthol from day one and has shown no interest in anything else. She gave her vv V3 to one of our sons the other day and started using the cheap eGo type pass thru I bought her for a back up. Said it was good enough for her. Last night she mentioned she needed another back up. I told her I had one and she was OK with that. About 15 minutes later she proclaims that it's a good thing she's not into vaping that much because there's alot of really cool devices out there. You have to understand she is very free with the money when she's spending it. I asked her if she had been doing some research. She said "no...I was just looking". I see storm clouds on the horizon!
