I've now had the ArGo for a few days now and it has been a fantastic little vape.
This is my 3rd(ish) vape (also had a Pax 2, Mighty, and several Dynavaps) and I think this one is my favorite right now. I've never tried an Arizer product before, but I really enjoy the vapor it puts out.
The size is perfect for my hands and it doesn't get that hot. I think back to my Pax 2 and how hot the whole thing used to get. During the summer I would have to set it down if I was vaping outside. The main area that heats up on this vape is around where you'd expect (the heater vents on the right corner), but holding it the correct way on the sides yields very little heat on my hands (or they aren't that sensitive).
The vapor it puts out is really pleasing to my throat, which is accustomed to the bit of muscle that Dynavap vapor puts out. It also tastes great, thanks to that all glass vapor path. I like being able to step up the temp as the sesh goes on or just start and end it at 380f. It isn't as milky as the Mighty was, but it will still get you where you need to be reliably like @
wisausnk said. I honestly like that it doesn't put out a huge cloud to add to the stealth factor.
The battery lasts quite a few stems, usually 5 or more depending on the temp and sesh length. I love that it takes 18650's. The heat-up time isn't terrible, I usually pack a stem while it's heating and it will be up to temp by the time I'm done packing.
If I had a criticism about the device, it would be the amount of scoobs that I get sometimes. It isn't that bad (especially if you put a bit of a nug at the bottom), but if you finely grind your material it can go through the little holes. The Mendo Mulcher that came with my vape chopped it up a bit much, but my Cali Crusher makes it just big enough so it's not that bad.
Very happy with my purchase and will update in a few months if anything changes
