Here is my experience after two sessions with the square Pro, and maybe everyone can give me their input, as we are somewhat new to vaping. This whole thread has become a bit unwieldy to go through, so please bare with me if some questions have been answered before (I tried looking, promise!)
First Session - single user
- Just wax placed on the pads, and loaded into square.
- Found that none of the preset temps (forget what they were) produced any vapor at all.
- Had to plug it in and increase the highest temp to about 460 or 470 F to produce noticeable vapor
- Device got really hot after a few pulls. Eventually, the mouthpiece also would become very hot.
Second Session - 4 users
- Herb in all chambers, medium grind, packed not too tightly
- We found that the first hit after initial warm up would be intense and strong, even at the lowest setting at 360 F.
- Subsequent hits after the first were weak, if any vapor at all. So we would need to bump it up to 380 to get anything. Even then, it seems to be very weak with long prolonged draws. It seems like this is too high a temp and will cause combustion, so either its not an accurate temp or the device isn't heating?
- Battery was charged between rotations, so was pretty full the whole time.
- Device would become extremely hot after a few hits, almost to the point we couldn't hold it.
- After a bowl each, we found chamber one to be almost charred in the center. This was the first bowl in the rotation, so see the second bullet point above. The other 3 bowls were still fairly green in color. Forgot to take a picture.
Overall, a bit disappointing, to be honest.
Questions we had:
- There is an intake vent near the heating element. Are you supposed to hold this as a "carb" for the draws?
- We know you hold down the button until it vibrates before drawing, but are you supposed to continue to hold down throughout the draw?
- What have you all found to be the ideal temperature for both herb and concentrate?
Edit: By the way, this was a "Phase II" model running the most up to date firmware 1.0.59
