Loving the live waiting list for this. I literally watched my name move up the list while Dynavap has only told me "it's a comin!". The race to 420 has begun! All jokes aside, I wish that more business used something like this so that you know where your order stands. Bravo Pipes!
I'll have to chime in and retract my previous vote. After seeing the issues users are having with charging, the small increase in cost would be more than worth it.
I'm sure someone else will chime in, but I should have a 21 coming soon to test (and am also on the list to order the hotshot) in case you don't hear back.
