I received my contest win today!! I love everything about this vape.... First off, easy to use right out of the box, battery life today has been awesome! The fill hole is larger than my smok and easier to fill... The clicking airflow works great, as I sometimes had trouble adjusting them. The vapor production, even trying a 50/50 juice at 80 watts was perfect, and wonderful clean taste with the Scion 2 tank.... The menus are easy to use and the mod is a bit smaller than I thought it would be, and perfect size with side fire, even with my smaller hand... Not heavy at all... The only thing I haven't done yet is change a coil, but even with a lower liquid level, no burnt taste... I love it!!! Thanks so much for such a great product
