I don't notice warmer vapor... touching the carto it doesn't seem to get nearly as hot as a LR atomizer. Why, not sure. It goes through the juice though and why I have a head buzz from them...
As far as battery life it seems to me that it will reduce the lifespan on the battery mostly because they drain more juice. Any battery can only be charged so many times, and they gradually lose their ability to retain a charge....Whether they actually ruin an ego battery... not sure.
The way I look at it is this. If they reduce the life on my battery - but I like them - then so what. I will simply buy more batteries. If they ruin them - then that would be a different matter.
Thanks for the info. Sounds like they're ruining eGo batteries, according to Squids' msg above -- LR atties, that is. Don't know about the LR cartos.
I'll just put two eGos in my mouth if I feel the need to get a bigger throat hit. Have been doing that lately, and it's pretty cool.
