I've been using my Haze Square for a few days, since I got it back from having the seal repair done.
It's taken me quite a bit of experimenting to get the load/draw right.
Based on what others have posted, my experience seems to be a bit different, though. I get no vapor to speak of until I hit 400F. So I've changed my temps to start at 400 and go to 450. I'm using medium grind, packed loosely, filling the bowl about 3/4 of the way. Long slow draws work best, and it still helps to squeeze the unit together while drawing. I've tried other loads/draws/temps, but this works best for me, so far.
I'm happy with the vapor I'm getting this way. It's very tasty, and hits hard.
I can get 2 or three draws from a bowl, then I have to open the top and stir the contents. Then I can get 2 or three more draws. I keep this up, stirring and slowly raising the heat, until the ABV is finally all brown and dried up. I'm getting 8-10 draws from a bowl this way.
Since I'm finishing at 450, though, the unit gets rather warm by the end. And the battery is halfway used (approx., based on the color of the LED).
At that point I'm quite ready to put it down, though, so I stick it on the charger and when I get back it's fully charged. Sometimes the red light blinks while charging, sometimes it doesn't.
Needing to stir the bowl makes using the Square a bit clumsy, though, because popping off the top is a difficult process and exposes all 4 bowls. For this reason, I'm mostly just using one bowl, vaping it out, and then refilling.
I guess I could fill all 4, take a couple hits from each, and then open it and stir them all... but that's a hassle, too.
I'm finding that the Square hits harder than my Dual V3, but doesn't last nearly as long. So I think the Square is going to become my "finisher." Get started on the V3, then finish off with the Square to really put a cap on it.
The unit seems fragile to me, despite how bulky and heavy it is. There are small parts taking quite a bit of load, and I'm fairly certain I'm going to break something eventually, with all the spinning and prying open required. I guess we'll see.
And the mouthpiece is loose, and will definitely fall out and get lost.
Using the Square is quite a different experience than using the Dual. And it's my first convection-only vape, so I think my initial expectations for the vape were a bit off. I was thinking of it as the next generation Dual, but it's not that at all. It's a different device, for a different purpose.
It uses a lot more material than the Dual, but it hits harder. I'm not sure what the upshot of that is yet, over time.
Anyway, I'm reasonably happy with it, and I think it will find a place in my day, alongside the Dual.
