I have most of the big boy toys, so I can set up almost any combination you would like.
Hands down, this is the best vape.
The voltage on the little eGo bat is regulated, so from the first hit to the last it hits the same. The atty is a modified LR 510-T with an Avid Vaper drip shield wrapped around it.
Spent the weekend dripping "Lime Ricky" through it. (never had that many Lime Rickys before without getting falling down drunk)
In time you will learn how to get exactly what you want from almost any PV.
