All depends on what you put on the dav. Throw a tank or smileo on there and turn up the voltage. You will notice a difference over your stick bats. For me it was a very pleasant difference. Personally, with the clearos, all I notice is that I can get my full drag quicker with my dav over the stick style. Seems I have to drag longer which results into more air in my vape with my stick bat. Now this might have something to do with my stick bat being an auto, and my dav being a manual. Because I hold the button for 1 sec before inhaling, warming it up a bit.
