Actually, I lose less juice with the eGo than say the VP2 or mega batts. The eGo uses up the juice and noting extra in cart or in atty or even in the back of the cart (where you breath in ) If you take the back piece off of the cart that goes into your mouth you will have some juice there and in my video on youtube that I show how to clean the 510 cart, I always have some juice there. Not with the eGo. I took off the back piece and only one little droplett was on the inside. It was condensation not juice. I am happy with the eGo so far, just would like the 10+ hrs that Mik gets, But I am NOT a light weight to vaping. Specially if I use 5 or more ml's per batt usage..
Hey
well, it seems you are a really heavy vaper - from what you report on juice consumption.
Im not a light vaper, but i guess over time i have gotten used to just being able to leave the ego - or leave the "habit" of wanting to drag on it. Eventually i think thats where we are all heading - at some point it becomes "routine" , just as smoking analogues where - however, since this has no tar, etc, then it IS easier to actually forget about vaping.
So yeah - its difficult to say how much battery life you "should" be getting. In the end though i wouldnt worry too much about it - as long as its no hassle to use, and it lasts you for X amount of time stabile, and that X amount of time is something you can count on, AND that X amount of time is impressive to you, considering the devices size - then its all good. Thats all that really matters, i think!
But it does deliver the best taste/TH ever, if you ask me

Mm-mm-m.
