@Entheos Hex - Thank you for the explanation and tips with the settings!

Yay!! I now see the location of the air inlet

I needed to pull off the steel condensor tube to spot it, thanks. Have to iso soak this tube anyway

Edit: Separated the swiveling bowl for cleaning. Someone at Entheos was a fan of the Haze Square! Those teardrop shaped flow redirectors are clever, almost like a gear down mechanical linkage, flowing from wider diameter bowl while changing direction to smaller tube. These two bowl parts are either ceramic or super dense PEEK, they absorb most of the vapor's heat during this turbulent flow direction and width compression changes, ouchy ouchy, don't touch me there

I usually don't turn mine off, you can leave it on and lock the device by clicking fire three times.

Ah so if you were to let it sit without use for long periods of time (days or even weeks) the battery would slowly drain, hopefully not an issue for most people if so (and hopefully no ill affect to the screen here, as another mod I had became too dim from this issue)

Let me put out engineering marketing mumbo jumbo haha

The convex design features three distinct concepts:

1.) Air Intake and Vapor Exit Heat Exchange: Incoming cold air interacts with the outgoing hot vapor. In theory the incoming cool air helps cool down the outgoing hot vapor and vice versa, the outgoing hot vapor helps pre-heat the incoming cold air that goes to the heater.

2.) Residual Heat Recycler for Heating Efficiency: As per the photo you see above, the intake of the ceramic piece is actually not visible, this is because it is located on the other end from where the visible inlet is. What this does is air is forced to pass along the whole outer surface of the ceramic housing before making its way to the heater. In theory, the incoming air picks up lost residual heat before even getting heated by the coil itself.

3) Slow Roast Bowl: As per Bernoulli's principle, which states that in a pathway with varying volumes, the fluid (air, in this case) passes slower where the volume of the pathway is larger. So in theory, the heated air passing through the material slows down while going through the bowl, which contributes to the design's powerful extraction.

Sorry but I have yet to confirm if there is any battery drain going on when leaving the batteries inside when not in use. Most of the time with my personal units, I leave the battery in and no signs of screen damage. I don't think there is much battery drain if any at all actually.

Lose battery doors, that would really upset my OCD. Resuming hold position.

@Just Justin You incite me by talking about hash like that this looks great

Ha don’t mean to incite or do I? Can’t help it, I get excited when I’ve found a vape that makes vaping H2O hash easy, effective and practical. Because H2O bubble and dry sift aren’t as pure as other “modern” concentrates, it makes it rather difficult to vape them effectively and they’re very few vaporizers that can do it well and dry herb too

Love reading about the science and engineering behind the device and how it cools itself and uses the excess heat to pre- heat the air. Also, thanks for the pic of the insides, wanted to see that without taking apart the device yet.

One of the best examples of cooling/pre-heating air intake recycling like the ConVex was the Ghost MV1 vaporizer (RIP). It’s heat-sink mouthpiece assembly pulled cool air in, simultaneously pre-heating the incoming air to the oven by picking up excess heat as it passed around the heat sink and cooled the heat sink in the process

Just received this unit today and I am very pleased. The function is really phenomenal right out of the box, I had no issues diving right in. I really enjoy the design and find it very easy to use.

As stated the stock screen in the chamber is very flimsy and falls out very easily. Another thing is the battery door, it is not attached firmly to the device. If I were taking it out I would consider putting a rubber band around the door.

Really a great vape and so far see it behind a top portable within the personal collection.

How would you describe the vapor experience? Is it like a more portable Bowle? Might you have a chance to try it with hash? Cheers mate

Knew I shouldn't try another mod based vape, my bad

Hi ChooChooCharlie,

What problems are you having currently? How can I help you?

The 'No Liquid' error is a bug that we've encountered as well and something that we've brought up multiple times to YiHi, the chip manufacturer that supplies us with the chips. It usually disappears after a coil reset or sometimes just taking out the batteries. The 'no liquid' is the chip's built in dry fire protection for mod vapes intended for e-cig liquids which we have specifically asked to be deactivated but somehow it forces itself back on during rare occasions.

It seems that the metal stem was not put in correctly in your video.

Please refer to video here for assembly guide:

Hey, it's not you, it's me

I can't deal with these style vapes, but many folks can

Oh well, I had my hopes up with the vapor path geometry

Good luck and salamat

@RxPlorer the experience reminds me of the portability of the firewood series and function akin to a splinter/510 vape. I have not used hash in it yet but can. What variety were you curious of hash that it would work with?

Received ConVex 1.0 today, just tried it once, but here are my first impressions

Very clever, very small, very effective

Still needs work with "fitment" issues, a bit janky when opening battery/stem door, especially by accident. Maybe a more secure vertically aligned rail system with better magnets?

I tried Bowle pot after reading prior posts with a beta unit. I couldn't close door with pot inside. So, I used S&B capsule, it fit just fine. This pivoting bowl door/hatch reminds me of the old DaVinci Ascent bowl swivel out design. Clever solution for Bowle-like top-down heated air, without a removeable stem, however the Bowle's design is easier and more stable IMO

Vapor is surprisingly cool, and vape's base gets quite warm after a while. That warmth means the right angle turns to stem are doing their expected vapor cooling job. Leather case would be nice I suppose. Seems like an easy disassembly, iso soak parts, steel and glass

I sliced wrap on battery inserting, and bent the slicing contact "spring" in the process. Positive up, but that's where the spring is...no spring on negative side where I expected it. So, need to push up battery against upper positive side first, then push in. Oops. Had to pry little spring out to make contact after my blunder. Suppose I shouldn't use that battery any longer

I'm mod-challenged, but this unit came set a 210C, so I went for it. Difficult to do a burn-off with this design, at least for me. I did cigar puffs to reduce the nasty off-taste. Every heated coil vape seems to stink in beginning

Push and hold to fire and draw, pretty simple. Warmup fire for 5 seconds before drawing is helpful

Nice advantage I noticed with ConVex so far -- requires shorter duration draws than other convection portables I've used, good clouds, AVB is toasty, no stirring of course with capsule

glass stem is height adjustable with little notches, can lower completely for pocket. Other than the Hopper, this may be the smallest and lightest on-demand convection vape?

The Delta3DStudios nearly universal silicone WPA fits on the stem:

I like the glass art… very interesting!
