After using the 510 and PCC for about a year, the Ego has really changed my vaping experience. I still switch out the battery every few hours out of habit. I've been using them for about a month now and I've only seen the dead battery light blink three times. And that was after 4-5 hours of use. Yup, I'm a medium to heavy vapor these days. But it's nice to know I can go out with two ego batteries and not have to worry about them dying on me of if the PCC will keep up with my usage.
When I went to see a movie I always had my PCC at the ready to charge the battery while I watched the movie. Now I know I can vape on the way there. Vape some on the movie--shhhhh!--and still vape all the way home without having to worry about it dying.
I went a long time trying to avoid buying a mod just to get good battery life, but now I know what a difference it makes. I'm not ready to trade up to the mega ego batteries yet, but that'll probably be the next step.

P.S. Now if they just didn't come in so many wonderful colors! Now sure which one to buy next.
P.P.S. I always use two batteries and have a new one as a spare. Yes, any battery can die at any time. The 510's were very reliable...unless you drip juice on the switch that is! I'll smack myself on the head if that happens with my Ego!
