Absolutely incredible
I've been obsessed with dhv's for about three years now since retiring from the military. Dynavap was one of my first experiences and continues to be one of my favorites. I reach past my battery/stem based devices, ball vapes, and even my "portable ball vape" in order to use my dynavaps on a daily basis. I still catch myself just looking at them after use thinking "wow!" Highly recommended and keep up the great work!
