I have an Extreme Q and it's my favorite vape of all... but I use my UD WAY more than the Q since the UD arrived. Once warmed up, the UD is just so quick and easy to use, as well as significantly more economic.
And regarding Dave's wood work, you'll find yourself holding and kneading the warm, finely carved wood in your hand, connecting to the piece in a way I never could with my beloved Q tower.
And I continue to be impressed with the thick clouds.
Also, couldn't agree more with CaptainDDL re: milk from my BDay vape, how there might actually be bigger clouds from another model, and Dave's killer service.
I bought one of the discounted Vaper Tamers from DaBudda for $15 and it rocks with the UD.
I would happily buy both the Q and the UD again.
Take the leap, you will not be sorry!
