@Skunkport: What about the Bernoulli principle without the condenser?

Which means you don't get as much air through the tip. You are in effect skipping the tip and getting your air from the hole. Gee, you don't need the device at all for that, just breathe.
We have discussed this before and the narrower your stem is (and the smaller the air hole) the more negative pressure you will get at the tip, but that isn't how the VC is designed to work and is more a happy accident for those who may want to skip the condenser. That doen't mean it won't work at all, it just means it won't work as well.
There IS a reason there are no air holes in @stardustsailor stems.

What about it? You don't need the bernouli effect to create low pressure to draw vapour in, your lungs are creating low pressure to draw vapour in.
A hole is a hole is a hole. You're drawing air in through the carb hole with the condenser, the only difference is that air flows up to the tip end of the condenser then into it and through to the mp.
Without the condenser you'd draw air from the carb hole and from the tip, depending on your draw speed and size of the hole.
You guys don't need to bother thinking this through. You don't need to bother taking my word for any of it or thinking through the Bernoulli principle.
Just take the condenser out of your M and see for yourselves. I just did. It works fine.
There's a reason they named it the 'condenser', not the 'Bernoulli effect tube'.

The cool fresh air flows along the condenser towards the front, before mixing with the vapour. This causes the hotter mixture inside the condenser to condense - hence the use of the name condenser. The effect of this condensing helps cool the mixture headed to your throat and collect the nectar. At least that is what I think is going on 
Case #1 : No carb hole or a fully closed one ,with or w/o a condenser,
(as the latter does not play any role without a carb hole present ).
By no means the human lungs can create enough negative pressure to draw vapour in with that
VC setting ,at least with ease and comfort .From the other hand the facial muscles are the best alternative for creating high negative pressure at this case.Mouthpulls are not the same like inhaling directly to lungs.Draw resistance is quite high.
Case #2 : Carb hole fully or semi open and condenser.
Negative pressure is created at the chamber due to Venturi inside the device.
Draw resistance is rather low .
Case #3 : Carb hole fully or semi open and no condenser present.
Negative pressure can be created by the lung ,rib cage muscles and diaphragm .Still the incoming air ( a fluid ) will enter the device by the means of the least resistance route .It will enter mainly from the open carbhole and not from the tight gaps between the cap and tip.Thus only small amounts of vapor will be inhaled.Probably breathing through the nostrils is a far better idea than breathing through the VapCap.Lot easier at least.
Cheers.

1) I use mine with the carb fully closed and I don't use the mouth method, I just suck. It's how I've been using it, through my little bong, from the start. It's really not that difficult, I suck up the weed into it like that too. I've never done this mouthpulls thing with anything ever, I've always just inhaled, first I ever heard of it was here.
2) The amount of negative pressure, if any, created by the venturi effect over such a minuscule narrowing of diameter is negligible. Draw resistance is low if you have the carb hole open because you're sucking some air through it.
3) Even with the carb hole fully open you draw enough air through the tip to get good vapour. Try it. Science and debate are perfectly fine but at some point you have to try an actual experiment to prove your theory.
I've smoked a bowl through the M with no condenser and the carb hole open and it worked perfectly well. Reality.
Oh and just an aside for those with cars - If you see those little 'air intake venturi effect inserts', don't. They don't do anything but restrict your intake.

Seems USPS knows when the recipient is a VIP!
From the feedback I've received from recipients, there seems to be a size difference.
I'm working on a solution to accommodate both sizes with a single wand model. Stay tuned.
For now, be confident that if you order a wand and specify the right metal type of your vapcap tip, that you'll receive a wand that will fit.
Nice post and video @Hackerman,
Question for all: Is there a failsafe built into this IH that if you leave something inserted past the 5th set of double clicks, that the unit faults over to a flashing Orange LED and doesn't heat? (removing and reinserting the object being heated resets this condition and heating continues).
If enough feedback is received on that question, I may share how I modded my IH to be HANDS-FREE!!!
(...) past the 5th set of double clicks(..)
2x 5 = 10 .....
(...) faults over to a flashing Orange LED(...)
An output ....
and doesn't heat? (..)
A canceling ( 0V ) Logic Level signal to a transistor /MOSFET /relay maybe ?
(...)removing and reinserting the object being heated resets this condition and heating continues(..)
...and a reset function !
Smells like a 4017 decade counter is on the use ...
Still ,that is not something everybody can do easily.
Probably I'm missing something here...

@Skunkport I'm not challenging you, but didn't you used to smoke tobacco cigarets/joints? Didn't you mouthful then? Just wondering if I'm taking you too literally, misunderstanding you or if you have misinterpreted someones description of a mouthpull. . .
And as someone who only uses the vapcap wide open with direct lung draws. . . I have previously tried without the condenser and with the carb hole un-covered and found it to be nothing like using with the condenser. There was proportionally far less vapour and far more fresh air YMMV.

Gosh......can’t anybody just count to 4, or 5, or 6, etc?
As for the condensor....I’ve always sort of appreciated its ability to keep my mouthpiece on.......

Yes, I used to smoke cigs and joints, no I didn't ever do any kind of mouthpull. I just took a drag straight into my lungs, held it, then blew it out. The only time I ever tried what I think you're describing is with cigars, my uncle said you were supposed to pull it into your mouth not your lungs. It tasted bloody awful when I tried that so I just ignored him.
I can try to video myself taking a drag from a vape if you want, I'm not smoking anything but I did it exactly the same.
It will be slightly more air since the carb hole is closer to the mouthpiece and the air from it doesn't have to travel up to the tip then back down, but it doesn't stop the carb hole from working. If it was designed without a condenser, you'd simply have a smaller hole or the hole further up.
Edit:- 5th set of double clicks because some of you don't seem to hear 2 clicks every heat, some of us do. There's a faint click then a loud one a second or 2 later.

Sorry, wasn't referring to the vapcap, but to the IH heater. It seems to have heat cycles in two phases. Insert vapcap, LED changes to red. First click LED changes to orange, then second click back to red. Then repeats. At the 5th set of clicks (5x2
) flashing orange LED and no further heat increase.Edit: reinserting the vapcap clears the condition, so it's not temp related, as it heats again at this point.
Just stuck a screwdriver in and it does as you said 5 clicks then orange flasher with no more heat until re-inserted, I used a wine cork drilled out for a hands free option, plenty of donors available if it singes over time.
Edit, a glass one would work better(less chance of pulling the cap off and dumping your load in IH)
No real harm done, the IH heater is completely sealed.

Thanks both!
Cool, I feel better about mine now!
For the hands free approach, I used glass.
Hey, either of you two interested in a custom water wand? A gift, my way of saying thanks for the assistance and not bashing my unique math skillz. PM if interested with shipping address and tip type (either SS or TI)

So how did you mod your IH to be hands free?

No idea, I don't have the heater yet myself, I've bought 5 vapes, various attachments, torches, butane, parts to build my own IH, bongs...I've got to mot my car next month, stopped buying stuff for now.
Small enough to fit in the hole, wide enough to easily fit a vapcap, deep enough to hold it securely.

Love it. Any idea what size the glass insert is? I don’t have my IH yet and would love to order the insert awhile also.
