A little update about my Prima's experience.
First, I like it, for flowers and concentrates. Vapor taste good, better imo than the haze, similar to the Alfa but less than miVape....only to get an idea (although it is a very lightly tainted with a rubber/plastic taste, maybe it will disappear...).
For flowers I use setting 1&2, rarely 3, and for concentrates I use settings 3&4. Clouds are enough thick for me at 2 (dry use only).
About stealth it's not great, people look at it (I got the orange, I love this color) while using in the street, never got this issue with my Alfa (never tried with the Haze!).
My button is not working very well all the time...i'm afraid to get issues in a short time.
When I extend the session the Prima shutoff before the 5mn autoshutoff (for the 2nd run, it completes the first without any issue, is it a overheating protection? or is it malfunctionning?
For my first tries i didn't notice the mesh screens must to stay in the bowl even with flowers, I took it off, put a screen in the bottom of the bowl and filled it and unit was working very well. Now I put the mesh screen in place all the time although I added a screen on the top of it to keep it clean from flowers debris.
Is it how it is designed to work (with the mesh screen in place all the time)?
I tried to replace it (since I only got one I want to preserve it for concentrates) with a nano domed screen...I was not really happy with the result, less clouds...so i put back in place the mesh screen, i think it add a bit of conduction.
I'm thinking about a water pipe adaptater...
All in all it's a great portable and I'm rather happy for the moment, the only downside is I payed a bit too much for a second hand unit cause I payed it in USD (he asked CAD), with the actual conversion rate i think the seller got more money than he spent to buy it...my mistake although (it's better to don't be too high before payment) and a great deal for the seller (just a bit bored the tool, replacement screens and 2nd mesh screen was missing), but i'm pretty happy with it and could recommand it for every vaporist!
