I've been using a 808-D-1 and wanted to try the ego since so many rave about it. Evidentally I am not a heavy vaper because a cart on my 808 would last me almost a day. I'm finding that filling my carts on the Ego isn't lasting very long at all. I am having to refill the carts every couple of hours with the same usage of the 808. Is this normal? It seems I will burn through way more juice on the ego. BTW, I am using the PTB made easy cart mod (straw with PTB). Any help would be appreciated.
