Well, in a rather twisted manner of operating, I actually just got a 510 automatic battery today

I started my vaping career with an eGo and have used different standard eGo batteries, a Twist and a KGO VV with cartos and cartotanks
After trying out the 510 with a standard size boge carto for a day, I gotta say I'm pleasantly surprised.
Nice vapour production, good enough battery life(for me atleast, 280mAh version) and I kinda like the automatic thingymajig it has going on with no button. It's not gonna last me forever, that I know, but heck, for around 8 it wasn't exactly an expensive purchase.
So yeah, I'm probably gonna actually try and stick with this for a while.
