My Roffu arrived today. I charged the battery, swiped the mouthpiece with an alcohol pad, loaded up the metal bowl and gave it a go.

It defaulted to Session mode. I tried to change it to On-Demand mode by pressing the Up and Down button simultaneously for 2s but had no luck. It heated up in Session mode for a while before I turned it off and back on again. I was able to change it to On-Demand mode on the next try.

I set the temp to 428F and pressed the button. It reached temp pretty quickly, but I cannot give an accurate estimate of the time because the unit had already heated up some when it was in Session mode. I will get a more accurate estimate on my next session.

Thinking that this vape is similar to the V3Pro I started out with 3-4 cigar puffs and then drew for about 10 seconds, medium strength and speed. I started feeling the vapor around 8 seconds into the draw. I blew out a huge thick cloud. Taste was average (but I'm not a flavor chaser).

On draw #2 I got a little confused, because I didn't get the haptic feedback when it reached temp for the second time (I need to test this further). The display seemed to indicate that it was up to temp, so I started drawing. I got little to no vapor. I tried again and still no vapor.

Thinking that the bowl might need a stir, I removed the top and checked out the material. It was clearly fully extracted. The color was a nice medium/dark brown with no visible green. The ABV was very evenly browned. It looked nothing like the ABV from my V3Pro.

The effects from the bowl were outstanding - another new vape signature to rattle the tolerance.

I will provide updates after I test a few more things with the controls etc. But at this point I am quite satisfied with the Roffu!

-------EDIT:

My second bowl was a very different experience from the first. Same basic parameters - metal bowl loosely filled to just below the rim, 428F, On-Demand mode. First hit I started with 3-4 cigar puffs followed by a 10 second draw. Another huge thick cloud. On the second draw I made sure that I got the haptic feedback before drawing, and I got another nice sized cloud. A third, smaller cloud followed that.

The flavor was noticeably more burnt on my second bowl, and the ABV was less evenly browned. There were some green spots and some black spots, with some signs of tunneling. It was definitely more charred than my first bowl.

I think what happened is that I may not have waited for the haptic feedback on the second and third draws of the first bowl. That meant my second and third draws could have been at a much lower temperature, since it never reached 428F. On the second bowl, when I made sure to wait, I was hitting it at max temperature on all 3 hits.

That tells me that the Roffu has power to spare. It tells me that if I set the temp lower I would probably get more evenly browned ABV and better overall flavor. But I can also set it to max temp and push the ABV to black.

Things I already don't like: The metal bowl gets scorching hot when used at max temp. It can be painful to the touch for quite some time. I haven't tried the glass bowl yet, but the screen in my glass bowl is loose and falls out easily. I wonder how easily it will dump out with a spent load. I saw that Jerry's screen stayed put but Troy's did not (like mine). I also have some trouble getting the control buttons to register. I had some trouble turning it off with 5 clicks (I am very used to 5 click devices). And the vape tastes like the foam packaging insert right out of the box. I'm sure it will go away, but XLux might want to reconsider the black smelly foam inserts.

I tried the glass bowl a couple of times last night. The vapor production seemed a little weaker than with the metal bowl, but the vape still produced some impressive clouds. ABV was lighter and more even with the glass bowl.

More importantly, it seems like the Roffu doesn't always vibrate when it reaches temp in On-Demand mode. Here is the behavior I observed last night when using On-Demand mode:

  1. First button press - heating light flashes until the set temp is reached. Unit vibrates. Draw timer starts counting down from 45 sec. AFTER the set temp is reached.
  2. Second button press - heating light flashes until the set temp is reached. Unit does not vibrate. Draw timer starts counting down from 45 AS SOON AS BUTTON IS PRESSED.
  3. Repeat #2 above
It's confusing and I need to try some more to figure out what is going on.

Started Day #2 with the Roffu using the metal bowl and On-Demand mode. Huge cloud on the first hit. Super hot vapor and a big cloud on the second hit. Little to no vapor on the third hit (bowl was fully extracted). ABV had a few black spots but mostly dark brown. The Roffu hits hard.

I did get the vibration on the second and third hits. I think it was because I waited long enough between hits to allow it to cool down some..?

Both the glass bowl and the metal bowl get EXTREMELY hot during use. It prevents me from re-filling right after a bowl :(

It makes me wonder if there is some conduction going on. I'm not sure that the material comes in contact with the extremely hot bowl for long enough to produce conduction heating, but I can tell you the bowl (and the area around the bowl) gets way too hot to touch after using the vape at full temp.

-------EDIT:

I followed the cleaning instructions in the manual. They recommend a burn off cycle for two minutes at max temp after a cleaning.

I turned it on with an empty metal chamber, set it to Session Mode, and let it heat for two minutes without drawing. After the burn off cycle the metal bowl was EXTREMELY hot. No hot air was drawn through it. I can't see how that wouldn't cause conduction heating, unless it doesn't get quite hot enough...?

I am not able to test this with actual material in the bowl right now so I can't say for sure.

-------EDIT #2:

There appears to be a bug in the Roffu software that prevents it from vibrating when it reaches temp in On-Demand mode under certain circumstances. If it is NOT the first button press, and the user has NOT changed the screen in some way, the device will NOT vibrate when it reaches temp in On-Demand mode. If it IS the first button press, or the user HAS changed the screen in some way (clicking 3 times to get to the puff counter, or just allowing the device's auto shutdown timer to kick in) the device WILL vibrate when it reaches temp in On-Demand mode. It appears that the user must actually go to a different screen, not just make a change in the main screen, in order to "reset" the vibration function. That means you can't just lower or raise the temp in the main screen, you actually have to go to a different screen (like the Puff Counter screen) and back to the main screen to reset the vibration function in On-Demand mode.

Ah yes a big flaw of a capsule-based system, and I guess you have to use the capsule here, even though it's not really a capsule it is a removable chamber, but you have to remove it to empty? I wonder if something like an Arizer stem could connect and become the bowl and vapor path?? Look forward to trying it out soon myself...

You don't have to remove the chamber to fill or empty it. Once you remove the top section (mouthpiece and cooling unit) you can empty the chamber by just dumping the contents. The chamber remains snuggly attached to the heater.

I see no reason that stems could not be adapted to the heater. I got rid of my OG Solo years ago (after many years of faithful service), so I don't have any Arizer stems around. I know the OG Solo stems would NOT fit in the Roffu.

But if you look at the Roffu's glass chamber it is just a short glass stem with a screen in it. It fits neatly inside the cooling chamber/mouthpiece unit when you put the lid on, but I see no reason that you couldn't forego the whole top assembly and attach one long stem w/screen directly to the heater. The stem would just have to have the same ID/OD as the Roffu's glass chamber.

As it is, you could (technically) forego the top assembly and just draw from the chamber, if you had asbestos lips. Do not try this! :rofl:

The point is that the whole top section serves only to direct and cool the vapor.

I think you'll see what I mean as soon as you get one.

Haha yeah I actually kept the bent stem when I sold my solo way back when, it can be used with quite a few vapes with silicone around it, just thinking of a possible potential mod I guess convection tera style which I never got to try...

The point is that the whole top section serves only to direct and cool the vapor.

Yeah I know, I'm not really looking to get rid of the top section, I think it looks like a pretty solid cooling unit with that U-turn bend, I was just thinking about it theoretically... But if the chamber stays attached to the unit to empty and load bowls then there's not really a problem here!

I saw Unklmark using a hula stem and a 16mm tube on Instagram. Don't know if that is a mark-style modification or what. Anyway seems possible 😃

Haha yeah it is a mod he did, he was using some metal piece around it as well, he has a lot of random parts...

So according to the Xvape website the metal bowl is made out of stainless steel, not titanium like I've seen some people claim. Not a problem imo but I just thought it would be good to get a definitive answer instead of just assuming it was titanium.


Edit: saw that an earlier commenter caught that detail. I just finished watching some other reviews that stated the bowl was titanium so I thought I'd chime in.

This hard shell EVA case works pretty well for the Roffu:

AGPTEK Carrying Case, EVA Zipper Carrying Hard Case

The case will hold the Roffu snug if you put it in the internal elastic netting, but that makes it hard to remove it without knocking the cap off.

Otherwise the Roffu fits in the case outside of the internal plastic netting, but the vape will move around a little in the case.

Mine has arrived, currently undergoing many burnoffs (unfortunately very necessary and tedious with such a short session timer) but the design is pretty impressive, it feels nice high quality, and thoughtful, I really like the colors (mine is blue which I think goes well with the white on top and bottom) and the slick brushed metal finish (though it is definitely slippery compared to those rubberized finishes if that is a concern for people, but I prefer it) The design with the removable chambers is pretty cool, not really a capsule indeed, just a fully removable cleanable chamber swappable for another material as well! The cooling unit seems nice and not too complex though I put it together wrong and couldn't figure out why the airflow was so restricted lol once everything has neutralized it should be very nice, but there are a lot of parts and surfaces, within the cooling unit, so I could understand the benefit to going without it, but I'm not really planning to mod etc. The accessories that come with it pretty impressive, a nice scooper tool with a brush on the other end, plastic funnel, nice pouch, with cleaning supplies, even a grinder! Also the tech is pretty cool, it's not always vibrate attempt, because it is still at temp, or close enough, there is a meter to show you that, it only needs to heat up and vibrate again if you wait longer between heads, need to press the fire button to exit stand by mode as well first (holding up and down buttons switches between session and on demand mode though you need to be precise btw)

I've been getting very evenly roasted ABV with the Roffu if I stir once or twice during the session. The roast is much more even than with the other convection vapes in my rotation. Unfortunately I wouldn't call the Roffu "stir friendly", as I invariably end up with some material on the ledge outside of the bowl. The ledge is flat, and the bowl is extremely hot, so trying to get any spilled material back into the bowl is essentially futile. And, because of the heat, I can't really put my fingers around the bowl to stop material from spilling when I stir. So a very careful, slow stir is required.

I fill the bowl loosely using a funnel. I've been switching back and forth between On-Demand mode and Session mode. They are equally effective. I use max temp (428F). First hit is a nice big cloud. Second hit is hotter and an even bigger cloud. I stir after the second hit, and the third hit produces a much smaller cloud after a longer draw. ABV is then a very even medium to dark brown color.

I am still dialing in my technique with the Roffu, but I can tell you that this thing is a BEAST.

Metal bowl, 428F, mostly using Session mode now.

I slowed down my draw considerably and got even bigger clouds with even darker ABV. Really close to combustion. Some "smoke" coming out of the bowl when I stirred, probably due to conduction.

The glass bowl "tames" the vape somewhat, but huge clouds and dark brown/black ABV are still possible with higher temps.

I may actually have to dial the temp down a little bit. As it stands right now I am getting too close to combustion at max temp.

Comparisons are inevitable, so I guess a separate thread is needed for that, but I can say that the Roffu hits way harder than the V3Pro. It can match the TinyMight in cloud production, just maybe not on the first hit, and not with the same cooling.

This thing has lots of power, gets really hot, produces huge clouds, and extracts thoroughly. I'll let others weigh in on the flavor.

I have found out that pre-production test units were supplied with a Ti bowl but the retail version has now got a stainless steel bowl instead, this material will lead to more conduction than Ti and maybe the reason for the change, not just pricing. A Ti version would have been great as well for a slightly different vape signature...oh well.

Can it produce clouds below Benzene boiling point ?
Below 176°F...? I'm sure that I will never find out. I did vape a bowl at 396°F and got huge clouds and dark brown ABV.

It would be nice if they offered a Ti bowl as an aftermarket accessory.

I have no doubt that the Roffu can combust at max temperature in On-Demand mode. I just went for a third hit with the power still on for about 6-8 seconds into the draw, then shut the vape off and continued drawing. Very black ABV with some combustion flavor, but not overpowering, and not affecting the whole bowl. But enough to tell me that if I kept drawing with the power on I would probably have combusted the whole bowl.

Beware - combustion potential :(

I had vaped a few bowls at 396F with great results and no combustion. Then I wanted to go back to full temp mode for another test.

WOW

My brief use at 320F did seem impressive, with temp control always being so relative

I tried a (metal) bowl at 320°F. I am usually a high temp vaper, so this was not really my style.

I drew slow and steady, like I do at full temp. It took a lot longer to get the vapor going at the lower temp. The first hit (a few short puffs then slow and steady for about 10 seconds) produced no visible vapor. Subsequent hits started producing vapor, and eventually I got some nice big clouds. I stirred a couple of times, and the ABV came out a nice even tan to light brown. There was never any hint of charring in the ABV or in the flavor of the vapor. Effects were outstanding.

The difference between 320°F and 428°F is pretty dramatic. At 428°F I can get a nice big cloud on the first draw, a huge cloud on the second draw, and the bowl is essentially spent by the third draw. I can approach combustion by the third draw.

At 320°F it takes a few draws to get vapor started, and I can get 4-5 nice clouds before the bowl is spent.

It definitely still performed well at the lower temp, but the cloud production was much less dramatic, and it took longer to get the vapor started.

If I was a low temp vaper I would try different draw techniques etc., but I think I will go back to the max temp.

Yeah I was using the glass chamber at 320F with a very light load coarse ground, and I got clouds right away on the first hit though it had been warmed up already twice with two accidental blank hits because I had the mouthpiece missassembled I could still taste a tiny bit, normally I would not take any sort of primer puff, just a long first hit and I don't think I would have any issue creating vapor even lower with this... However the taste was so awful I didn't go further, have not been able to test further, still letting it air out and running burnoffs, maybe this is from the packaging material smell?? It was not this bad with my xmax v3pro, but I am hopeful it will neutralize eventually...

Maybe try a baking soda soak.
My CamelBak water bottle has a soft silicone mouthpiece that kept the taste of the dawn dish detergent after I washed it. Baking soda removed the stubborn taste.
