I got mine today and it's absolutely mindblowing what this thing can do! The first thing I learned was that you don't have to hold the button down but about 2 seconds as compared to the usual 4 or 5. I immediately put Noalox on the threads too. Don't want it locking up on me. I put all my other batteries away. They just don't do the job for me anymore. Overall I'm VERY Happy and Content. I'd surely reccomend it to anyone that's serious about vaping.
