This is crazy, I know I’m alone, but I don’t normally care for Geek Vape. I ordered this because of the bottom airflow. Honestly I wasn’t expecting much, I was wrong! Geek Vape got this one right! I’m really enjoying the vape off this! Fantastic flavor, simple to build, I did have to swap out an O ring, but they included plenty, that was an easy fix. Now the O ring tolerance is great. The thing never leaks either, even when you dump your juice in. It’s Geek Vape and I don’t have a complaint. I’ll have to rethink them! Seriously do yourself a favor and pick this one up, you won’t regret it! Eciggity’s service was excellent as always! I placed many orders with them shipping is instant, customer service is outstanding! Don’t hesitate to order here!
