Boo yeah, got the DBV yesterday in the mail (USPS ftw... delivery on Saturday is always a plus), and I love it.
I had a lot of friends over to try it, and they were blown away. Only 3 bowls was enough to get a crowd of eight people pretty damn blitzed for a good 2-3 hours, and with a non-existant "zombie" come-down, it was all laughs and fun for the whole time.
That being said, I believe this vaporizer is best for solo operations, which is why I picked it up in the first place. I already swapped out the screen so I could drop the original in some alcohol to clean it, but damn... this is really doing the job nicely. I tested it out first and a small .1g worth was enough to get me lifted longer than my usual combustion lift-offs do. I also have some beautiful fruity nugs that smoke lovely.
I picked up a free 4-piece with the unit as well, and it's been nothing but good to me. After cleaning it out (although I think the paper trick is pointless, it doesn't hurt to do so) I ground up the bud and to my surprise a lot of kief collected right away. Maybe it's just the bud, but I haven't seen rapid kief collection happen that fast in comparison to a buddy's SharpStone grinder (I'd put it up there with Space Cases, although not as luxurious.)
Anyway, just thought I'd drop in and let everyone know that my first impressions with the unit are great. It's ease of use is awesome, the time it takes to heat up is awesome, and the amount of vapor you get with it is awesome. I found myself getting around 20 pulls, each hit having a great distinct flavor and distinct vapor coming out of my mouth.
The twist and lock feature truly is my favorite part of the vaporizer, I've heard a lot of bad things about people pulling out the whip in the unit, especially within groups... but this feature totally removes that possibility.
I could go on and on, but I'd rather just leave it at "Fuck Combustion."
