Ended up getting the opportunity to test out the Roffu, and it's not too shabby!
I've done 5 sessions so far. Two of which were On-Demand and the glass bowl. Two were session and glass bowl. Final one was session mode with the metal bowl.
First bowl the battery ended at 4.12v. I accidentally kept it on the charger for a few mins, so that ended up going up a tad. 2nd session ended up at 4.06. Ended up charging to 4.08 (accidentally again
). 3rd bowl ended 3.92 . 3.88 The 4th. 3.82 the 5th. So so far, battery life seems to do better than I had expected. 5 sessions so far and still room to go.
Even when doing on-demand mode, I still treated it as a session. All bowls were finished in one sitting.
I always started around 350-360f, and the first draw had little to no vapor, but I could absolutely feel the thickness of the flavor coming in as I took a draw. The flavor was always very strong. The flavor held through a few rips, and then starts to die off towards the middle of the bowl. ABV isn't ever perfect, but it is pretty dang good, and stirring definitely helps (and it's very easy to stir). It's not blatant hotspotting, it's just not a conduction/hybrid style roast. It's pretty good abv for a convection portable like this (don't worry, I got the pics).
I think packing down would result in more issues as the bottom would char a bit faster (you'll see evidence of this in one of my last screenshots).
The manual says it works best with long draws. I absolutely experienced this. I did not have much success with shorter bursts, which makes sense for a portable convection vape. Throughout a draw though, once it hits a certain point, it really spits out vapor. It can just take a bit to get there.
I've noticed a more firm draw tends to work best for me, and going slow like other convection vapes just didn't seem to give it the oomph. I'll revisit this though with more testing.
I would usually bump up the temp to around 375, then around 390 throughout the bowl to finish it off. One or two of the sessions I went into the 400s, but didn't really find the need to.
What I'm most impressed about so far is probably how smooth it is compared to other portables I use. Portables usually give me a pretty rough cough even without huge hits, but this one is pretty comfortable. The cooling unit does well at cooling the vapor, but just something about the vapor itself isn't too harsh. I notice I cough more with my Crafty+, not because of the heat of the vapor (the cooling unit is great there too), but just something about it. Same as most of my portable.
For the final session when I switched over to the metal bowl, I noticed it was helping my biggest gripe with the vape, which was how long it took to for that big vapor to start pumping out. I've only done the one session, so I'll need to check it out again. But if I can get those solid hits a bit faster, then I'd be pretty dang pleased.
One part of the On-Demand mode that I don't understand is even when I'm not pressing the button, the temperature circle randomly goes up and down like it's heating and cooling. Also, it only occasionally vibrates when it gets to temp when on demand. Always during the first heat up, and then randomly during other heat ups.
Not a huge fan of the mouthpiece and having to press the lips against it. It can start to get warm, and it's just an odd sensation on the lips for me. It's never gotten uncomfortably hot though.
So far it's really easy to keep the bowl clean with the brush, and to keep the mouthpiece screen clean.
The part that is probably going to require the most cleaning is on the mouthpiece itself where the vapor passes through the screen and then across to the cooling spiral.
Will be testing sessions throughout the night but just wanted to give some initial impressions as they were fresh. So far it's a pretty fun vape but a lot more testing needed to see if it'll find a good spot in the rotation.

Should be able to scroll through the pictures. The last two you see I got lazy with the stirring and pack, and ended up getting some noticeably darker spots.
