Systematic evidence based analytics is the basis of scientific assessment and finding objective information. With that in mind, I'm struggling with the evidence and BS flags posted rebutting the reasonable-ness of EVO temp estimates. Feel free to disagree with my position but let's try to stick with facts and objective information and be nice.
I'm sorry, I got to throw a bit of a BS flag here....again, I think. I run at about 1:30 on the dial, I def get full extraction, and I'm no where near 440F.
Just because the dial placement is "quite common" doesn't mean that you (and others) are fully extracting AVB. That's literally subjective feedback, inference and extrapolation; its also a false equivalency fallacy, an appeal to popularity fallacy, a sweeping generalization fallacy and a confirmation bias fallacy. The weight of evidence overwhelmingly shows most people simply don't fully extract their AVB (regardless of the vape); look at temps used, AVB pictures and feedback from most people! Unless the AVB is very dark brown (pushing black) one
is not fully extracting AVB.
This is basic stuff. And I'm not surprised most people don't fully extract their AVB because the high temps necessary mean flavors suffer and vapor becomes notably harsher. I don't fully extract either!. I also don't doubt that there's lots of cannabis/AVB extraction at the lower temps/settings used by
@Baron23 and others (including myself!)....
but that's not the point being debated. I haven't seen anyone post up a picture in this thread of dark brown to black AVB from EVO 1:30 dial settings (other than malfunctioning ones such as cracked bamboos), but if anyone has it by all means post pictures/details up.
Perhaps
@CANtalk unit runs cold as I have found the dial placement I use to be
quite common among other owners and that we all seem to get definitely, absolutely, well extracted AVB and are nowhere near combustion.
Well-extracted is not fully extracted (as mentioned above)... semantics/details matter and it's disingenuous to conflate those two things. By all means post up some pictures of your AVB! Put some pics to your words of definitely and absolutely. Vaguely comparing your use to others to infer full extraction is a big unhelpful assumption. Data and details matter. That's why I've shared data and pictures. If you're talking well-extracted then by all means there's no issues here, that's a personal value judgement.
Why would my unit run cold? There's no evidence of this. I've mentioned before I vape at 11 o'clock on the dial and get lots of clouds. It also can run up to 3 o'clock without combustion. This performance, the heater behavior and the results are in general agreement with what others report for usage with the EVO... correlating reasonably well with the VapeXhale temp estimates and with the use of other digital temp-set evapes.
As for the temps...either from VXH or on the heat sleeves that have a temp dial...I take these absolute temps with a grain of salt and to me its just a relative analog dial. If I want more heat, turn it up a bit. Want less heat, turn it down a bit. But as far as absolute temps....nah, I put no credence in that, personally.
I never said the temp estimates on the heat sleeves were "absolute"... where is this absolutism and inaccurate referencing coming from?? And why is it being done?? All along I've been posting ranges of temps and often using the ~ symbol which is
literally defined as "about". I've also used relative language and qualified such statements too, calling temps a "reasonable estimate". I've further supplied supporting evidence and information on multiple occasions.
Labeling the EVO design setup as a "relative analog dial" is misleading and only a small piece of the picture. The EVO heater setting and temperature control design uses long-proven reliable and accurate technology with a microprocessor controlled potentiometer setup and a temperature sensor, resulting in high resolution and low drift,

If anyone has any objective quantitative evidence showing that the EVO temp estimates are not reasonable then that by all means share it. I'm here to share and learn.
Finally, as with all full convection vapes that do not have an internal fan or air pump (think Volcano), absolute temp of the air at the load is going to be dependent to some extent on draw rate. Slower it should be a bit hotter, faster a bit cooler. So again, I view manufacturer data about absolute temps with full convection devices with a jaundiced eye.
Sure, there will be some variability to temp with air at the load depending on draw. A bit hotter or cooler as you say, but here again is absolutism that I never posted about or subscribed to. There are lots more variables with temperature estimates as well, such as the sensing technology, location, responsiveness, accuracy, etc. I have not said and am not saying that manufacturer data about temps are absolutely accurate. Rather, I've said they can be reasonable estimates, and subscribe to that... a good reasonable guide; it's a heater metric incorporated on so many electric vapes.
Let's try to be accurate in words, details and specifics; they matter because if we can't accurately describe what the context of our information is then the information is unhelpful. It's about the information, not the poster or individual. And it's too bad when responses stray into derogatory territory.
To overall reiterate, I never posted saying the temp estimates were absolute and I never said they were invariable. Thus far, I've found from the overall weight of evidence with the EVO that the sleeve temp settings are reasonable estimates. I don't doubt that, based on manufacturing variability as well as use variability, temp estimate settings may be a little different from EVO to EVO and owner to owner... but they shouldn't be hugely different. I never thought this would be controversial.
How much variability is out there from EVO to EVO and owner to owner? I haven't seen a lot of variability on one hand but no one really knows either since few have shared AVB pictures, details and heater/temp settings. I think all of this is an interesting topic and was simply sharing what I've found. Debate rooted in inference without supporting evidence and pictures like AVB is unhelpful ... by all means contribute to the knowledge base!
I'll vape at about 1 ish during the day, and 2:30 ish in the evening for a more sedative effect. I'm not near combustion there.
Makes sense and sound reasonable to me. I do the same and definitely find the higher temps more sedative.
Absolutely! Quoting temps for this vape is pointless .. In fact, since there is some variance in the devices, quoting the dial position is reasonably arbitrary, but it's all we have left to quantify the heat.
If people are comfortable estimating dial position to quantify heat (I think it is) then it's no different to estimate temp by dial position... it's all based on the same considerations and inputs. And I don't find estimating temps pointless since I can use it to compare the EVO and its outcomes to other vapes with digital temp settings. It works reasonably well in my experience... eg., the EVO at ~320 F is reasonably similar to other vapes I've used at ~320 F (and so on with other estimated temp settings). More info above.
I don't understand the tie-in to heater setting variance. Nothing is absolute, so variance in-and-of-itself is not unexpected. No one knows the amount of variance in the EVO, or other vapes for that matter (other than malfunctioning units are significantly off), so it's all arbitrary in the end. With that in mind, I find it's okay and reasonable to give temp estimates. Ergo, if dial position with the EVO is a reasonable of estimate heat/temp levels then temperatures can also be generally inferred from the dial position... you can't subscribe to one without the other.
Well this just happened! Second time breaking my hydra tube!! As we were arguing earlier, definitely not American glass! At all. I was swaying the tube trying to get the droplets of water out, and the mouthpiece just flew right off! Extremely thin shit man! I’ve never had a bong break on me without a drop or a smack. Very disappointed, I am definitely not buying another hydra tube for $150, theyre out of there fucking minds dude. Guess I am going back to the flowerpot after all, it was fun while it lasted (2 weeks LMAO)
Ugly

@macbill and a few others have reported having American glass break from being too thin, etc... it happens and American glass does not guarantee 100% quality unfortunately. I've seen a number of people report breaking bongs without a drop or smack... sadly
.
I totally understand being gun-shy on buying another expensive hydratube with that experience. As
@His_Highness @SatanLovestoVape and
@InhaleExhale all mention, consider China glass such as DHgate as an option. That glass is much cheaper, though my experience has been hit and miss with them too. Maybe a regular 18mm bong is the way to go, cheap, often local and as mentioned use the EVO inverted. Unfortunately all glass is a bit of a crap shoot no matter the source. My condolences, that's terrible.
. It's great and useful. I hope ur bad glass experience doesn't keep you from the EVO (but understandable either way, bad experiences are hard to overcome). Your contributions and feedback are most appreciated 
. I hope you get things sorted out and best of luck.
.
of experience. Flavor is such a subjective metric, it's difficult to give a straight-forward answer to your questions 
. Continued feedback on your EVO use is most appreciated; you're one of the only high temp rippers posting (I temp step and am not a ripper). Flavors are top notch 
. Just riffing on your use... I think if you go slow on the draw you can bump up the dial to ~3 o'clock and extract in one or two draws. Forewarning though, while no one knows how much, there will be an added risk of combustion. Sweet hydratube choice. Cool picture. And nice setup you have there

with the EVO for much of the night now. I read this post earlier and it was too much for me to process
