Well I have had my mini about a month now and thought I would review it. I received it in the states while on R&R and loved it as a bottom feed. Used it for about 4 days and headed back to Afghanistan, no issues with the TSA or anyone so that was good. After my 4 day trip from Nashville - Atlanta - Kuwait - Kandahar - FOB Wolverine, I had completely drain all 6 of my batteries lol and close to 30 ml of my fav blueberry cheesecake. Being my first true mod I was hoping for nirvana and expecting ok. Well jay is as close as anybody is going to get. The warmth and TH were so much better than my EGO, the taste came through so much more than ever before. I am a fan of atties but being a pilot as well carts work better in my aircraft. So after getting to my timeshare in this lovely country I pulled the atty off and stuck on the carts. I was surprised at how well it did even still in the bottom feed mode as Jay suggested top feed for carts. Well the next flight I found a reason why top is better all around in my case lol, you see there is a thing with pressure of changing altitudes often that the bottom feed doesn't like going between a takeoff at 6500 Msl and climbing to the height of 10000 Msl then down to as low as 3000 Msl before returning to land at 6500 Msl let's just say that bottom feed is auto feed. Juice all over my ankle pocket where I carry my beloved GLV juice in the battery compartment juice just everywhere. So I reworked the the setup as a top feed and put in the little orange ball and set screw. Next flight no problems with leaking, but the pressure made the bottle to hard to squeeze, it took alot of force to get anything into the cart, the solution to that problem came from here where someone mentioned they opened the tip of the bottle a bit. Now I am happily VAPING every flight and having my copilots trying to guess the flavor of the day. On a last note not once have I been concerned with this device holding up in a combat zone it is rugged and well built always ready to be abused by a soilder such as my self throwing it on the dash cause it's time to get to work helping the ground guys to just being in an ankle pocket with everything else in the world I carry, it has never missed a beat and not fired unless I was to stupid to notice the battery is dead. Keep up the good work Jay and Sara and thank you again for getting it put to me before I had to return to this Wonderful timeshare.
