Mine is premium vape or something and hers is something like eversmoke. They were $25 starter kits on groupon. I have now purchased a 2nd run on filters, shes still on her first run. Doing fine with the every 2 hours for the most part, some slight cheating on weekends when company is over and alcohol becomes involved but neither of us have come anywhere near a full pack in a day. Thx! As for the 3 hours or quitting at work or etc I posted before - Still just sticking with the 2 hours. its going well, maybe raise the stakes later but not fully comfortable with it yet. I do notice however that some of my 2 hours is up moments, I dont even need one yet. the addiction is weakening!
