My problem with the SE Gold is 2 hour battery life and constant filling. It doesn't hold enough juice in those iddy biddy carts. I get lots of vapor for 10 or so puffs then - refill. Yes you do get throat hit but I had to move on. I still have it and use it occasionally to make sure it's working still but it is mainly an "emergency" backup.
I also hate that I paid over $100 bucks for this at a kiosk in a mall but it was my first venture into the e-cig world and got me started so I can't complain there. It was enough to keep me off analogs for about a month until I got tired of refilling. I then decided to upgrade to a bigger, more popular e-cig.
What did you upgrade to, please?
