Sorry, I'm not sure about the o-ring.
You might have an unusually hot unit, but,
I've found that this vape can over-cook (euphemism) at any of the temp settings, just takes a longer draw on lower ones. So, when using any of them, be in tune with the actual production coming through, and power off before the end of your draw, vapor will keep coming for a bit. I stop even before any popcorn, thankyou.
Mine doesn't sit well in my glass, but most of my glass is cheap stuff, so I attribute it to that. I still get acceptable(!) hits. It also can tend to sound like the joint is 'leaking air' but that sound may also be air moving into the intakes. You might try the silicone mp that comes in the box? It is bulky/oversized, but might get you a better seal...
Thanks for info! I use the silicon mouthpiece and it sits better sealed into my 14mm female stems. I too am using cheap glass so not precise!
I find it is a lot nicer if I only have 2 or max 3 pulls from a chamber - I get popcorn on the third usually. Starting to do 2 big pulls and 1-2 smaller ones.
When you say you prefer dry glass, why not water bubblers?
Would an 18 or 18.8 mm female opening provide a tighter fit by allowing the fitting to swallow more of the silicone mouthpiece?
Also, I don't know if it's been tried or not, but have any of you had any luck with bypassing the stock MP all together and using a screened glass stem that actually sits in the chamber?
Similar to the tiny might I suppose, where the flower would actually now be packed into the stem itself instead of the chamber effectively isolating the vapor path to almost all glass.
Food for thought; I'd love to hear any ideas you may come up with.
The combustion on green may be coming from an over pack as well.
This little unit really doesn't need much in the chamber.
I have similar experiences on green as I tend to "cache out" in one lungful.
For now, just chalk that up to me packing too much.
I think an 18mm would definitely help - but it's fine with the silicon I find to help seal a bit better on the 14mm's. Will consider a 14mm male to 18mm female glass piece potentially, but think it's fine at the moment now I've been using with the silicon mouthpiece
Wow, the glass stem replacement sure sounds interesting. I do not like how the cap screen likes to come loose/fall off and sit on the bowl. I notice ddave has screens to help stop that apparently.

I have definitely been packing a bit too much - find better results with 50-75% chamber pack, and not tamping. It's a bit smaller size chamber than I would like, but it does the job after a few bowls.
I totally understand your thought but it's necessary to check the age if we sell vaporizers.
We have to make sure that minors can not purchase our products because it is illegal and we promise we will not keep your personal information.
I don't even have a driver's license. Do you post to Australia? I only have Liquor Land ID, which is a legal proof of age in Australia.
Can you please confirm where the white o-ring is supposed to go, that is included with the unit?

I really like the Vleaf Go for the price! But now that Xmax V3 Pro is out, I think this is probably worth the bit of extra cost - USB-C charge, replaceable battery etc. I speak to one user who owns both and prefers the Xmax V3 Pro, but has anyone else compared side by side yet?
but no problem
