I finally made the switch to vaping about 2 weeks ago. Started out with the Smok Stik AIO but have outgrown it quickly. The 2 ML tank just does not last long enough for me during the day if I am off. It is a great at work stick where I am limited in time though. A friend suggested the Smok Stik TFV8 but I have seen a lot of negatives about leakage on the Baby Beast and the Big Baby. Now the X-Baby is out with a top airflow but 1 less ml capacity and seems it may be worth it. Are all of these Smok tanks compatible with Smok kit 3000 mah battery? I have also heard the coil life sucks and I will be putting a coil in every 2-3 days which is not a financially viable solution. I was also told to get a box mod with a crown 3, but am worried about the batteries and all that since I am new. Don't want to burn the house down. So I guess what I need from you guys is advice on what to do. I need something that will last all day, (4-5 ml tank and strong battery) with a coil life that will not need replaced so quickly. I go through about 30-40ml of juice in a week to week and a half. Thanks
