I used it last night and really enjoyed it. I must have gotten about 8 or 9 hits off it, similar to the results I get with the Iolite. Henny, I was unable to get much for visible vapor, but the effect was definitely there in spades. The manual states to try and get a swirl of vapor in the box for maximum effect. I was unable to get this, as I didn't see much vapor. The vapor I got was light and wispy, and I got a little bit of vapor leakage from somewhere, but not enough to matter. I used up one load over the course of about ten minutes and 8 or 9 hits with one battery.
Things I like:
--It is small as shit! This thing just might get lost in my pocket!
--I love using the whip and watching the herb vaporize...getting darker, etc.
--It's the first vape I've used that got me whacked without much visible vapor (this may be user error), and I've had in the back of my mind the chase for invisible but effective vapor.
--This design is simple like the Launch Tube (LT), but has a refined feel that takes it out of the science project category, imo.
I don't have anything negative to say yet...it does what it should.
I treated it a little like a VG in that I kept stirring the herbs between hits. It's easy to stir with either a shake or a blow back into the chamber. This I like better than the VG because you can see your herb stirring and moving, getting into position for the next hit. I like the visual feedback. The ability to see the herb and move it like this (and its size) just might put it at the front of my portable lineup...but I don't want to get ahead of myself after just one use.
