I just got one. I'd rank it overall comparable with my Arizer Air and Solo, meaning it's in the top tier of portables. It gives a heavier hit (but inhaling much closer to heating action) than my Arizer Air and Solo. It seems to (or is claimed to) be all or mostly convection vs. conduction heating, which is rather novel or rare in vapes this small and effective. It definitely seems to pack that extra impact I expect from convection vs. conduction heating.
It's simple, well engineered and constructed, very effective, compact, temperatures seem well calibrated, and claims to be largely convection -- a winning combination. As noted, the only potential downside is that the mouthpiece gets hot, particularly if it's turned up high and/or used for longer than the 4 minutes it normally stays on (single cycle). And despite reports, it doesn't heat up as fast as cited (at least at the upper end of temps. that I use), with the temp. reading obviously at the heating element, not whatever metal heat exchanger is being heating. But it is much faster than an Arizer Solo or Air in giving comparably productive hits (at top-end settings).
