I'm happy with this purchase. The original tank for the Vaporesso Gen was leaky and hard to take apart. This one in comparison has never seen any leaks and comes apart smoothly, not stuck. There are complaints about excessive airflow and inconvienent sliding lids, but I never found those to be a problem only an upgrade. It took a few days to get used to the airflow but I can honestly say it's better than the tight congested feeling of the other ones and the sliding lid is very convienent, never had a prob with it accidentally opening in my pocket. The coils are a bit expensive compared to others but I find they work and last better.
Love it! Great flavor and an amazing cloud!
