Hi all, It's been a couple years since I've posted here. I started vaping about 5 years ago with a DSE901 and upgraded to the Joye 510 about a year later. About two years ago I started using the Ego 650 mah batteries with the Joye 510 atomizers and haven't felt the need to upgrade until recently. The old 510 atomizers would last me a few months with regular cleaning and the old Ego batteries were great for them until recently. These new 510 atomizers seem to be made to die after a few days and the Ego batteries have too much safety crap built in to them that limit how much of a "hit" you can get out of them. So, my question is about what most people are using now, since I have been away so long. My brother uses some Kanger Ecig that looks like a small baseball bat (too big for me). I tried some of the cartomizers he uses for it and they have given me nothing but trouble, leaking, dying and acting pretty weak with my Ego batteries. What do you all recommend?
