Well, I got my Stempod late in the mail late Wed, shipped out this monday, USPS priority across the continent, pretty good
I put a few sessions through the stempod and I must say
@supershredderdan you really made a hit with this one! 
Right out of the box, no modification needed, only to set your mod properly, and this thing can deliver "0-100 mph" quality convection vape real easy, and plenty much of it too!
Results and impressions are "early" but
very good so far, let me break it down if I could:
I started with my trusty evic still loaded with AF that I set up a stempod profile for real quick. From reading others' early reviews so far, I decided to be "conservative" with a measly 30w, TCR 285, and 380F. I decided to go with my new showerhead ash-catcher + j-hook "sherlock" bubbler combo with an 18/18M joint (which I have been enjoying much with my tubo, lately, which looks on in the background)
First draws, I got only light vapor, with nice flavor, but very little vapor. I noted a very slight metallic taste first (and I did "burn off" the coils before I vaped with them first) but I really couldn't notice it later on.
I noticed on my evic's screen, that during my draw, the watt output was staying
maxed out at 30w, and the temp was not reaching "protection" and hovering 20-30F under my intended temp....
so in essence I was running it in "watts" mode, and I was under-powering it. (air throttle was wide open btw)
So naturally, I had to increase the watts, I upped it to 35w and got my next basket screen ready.
That first bowl I loaded just like I do my tubo, lightly tamped rimless basket screen with a small mesh screen covering it. I was getting a slight browning in the middle of my flowers at first (even more than it shows in the pic), though not quite charring, far from combusting. With my full-lunged, watt-deprived draw, and no rotation of my stempod or glass stem during my draw, this is understandable. I wouldn't see this in my more successful, later loads.
The flowers of that first load, it was pretty nicely brown beside the little dark spots you can see. I didn't get a great cloud from this load, but @ 35w it was better. I managed to get a pretty decent cloud, but with raising temp to 390-ish, I saw my watt output was still maxed out @35w the whole draw, not quite reaching temp
My battery was already low, so I decided to give the stem-vic-pod a rest, charge it up, and load up tuboevic with some
moar watts in TCR mode to really see what it can do...
So a few hours later, full battery, smooth flashing over to tuboevic, just set a few simple #s: TCR 285, 50w, my preferences for the "clicks" (2 clicks to cruise, 3 clicks for edit, 4 clicks for step-cruise) and also the cruise / step options also.
I locked the coil at 0.121Ω. It had "set" itself @ 0.123 by default, not locked, but I used the live-resistance monitor to see the coil Ω was extremely stable, no wobble at all, and it was resting @ 0.121, so I inputted that. All this took about 3 or 4 minutes, I'm quite familiar with tuboevic, myevic, etc.
I moved over to my dhgate klein torus 14mm recycler rig with funkyjunky's 18/14mm adapter, and started at 390F. And the fun really started now! No more extra screen on top of my flowers, cruise mode, full open air throttle, I let the coil warm up for just 2 seconds before I take a long rip, and I pull the stempod & glass stem out of the rig to "carb it" and empty the rig to inhale my whole puff....
very nice! big smooth clouds, nice & easy...
I was making myself cross-eyed to observe the screen during my puff, but I saw the watts maxed out @50w for a while but it finally was hitting "protection" (or showing over the set temp, with tuboevic FW) and the watts output would throttle down to the 30-40s, indicating proper temp control function, to help avoid overheating / combusting
I moved up to 400F, and started twisting my SP around the glass stem during a puff on cruise mode to get the "swirl" effect and toast my flowers more evenly, and continued getting great puffs. The flavor was great on the first cloud, and it reduces a little from subsequent hits as you'd expect, but stays good and wasn't getting stale, over-toasted, burned-popcorn tasting...not at least until I would milk a good 10-12 puffs from a meager 0.1, 0.12g sized loads.
I had set a long cruise for 6 minutes, and after a quick swap onto a second load, I got a "device too hot" error on my mod
but that might have been from my over-enthusiasm, and also maybe from leaving it on "cruise" when I wasn't puffing all the time. On cruise when you aren't puffing, the watts bounces low as it should, but it still lets the CPU get warmer, so maybe doing short cruises, clicking off when you don't puff, would be better.
Those next 2 rapid bowls came out more evenly, with a much less pronounced hot spot in the middle. I don't think I even stirred, just swirled the SP.
We don't have lots of good pics of the SP deck up close, I think we could use those.
The middle part is paired with my 18/14mm adapter from the tubo evic here
And here above is the detachable, mid-section of the SP. Down this barrel is where your glass or wood stem, adapter, mouthpiece, etc is inserted. The o-ring serves it's function pretty well. It's a slight drag on a glass stem, but you can lift it gently for less resistance, if you like to twist. Maybe a little glycerin around the o-ring to make it glide too?
Supposedly you can remove this o-ring but that seems tough? I can see this being a "wear item" with heavy stempod use, I agree it would be a good idea for Dan to throw in a few extras in future orders
And this is the bottom end of the mid section, which slips over the deck and grips the o-rings on the 510-base, or build deck. With a twist, it glides over the deck with ease. Almost too easy, I wish when I was doing my "glass stem twist" during a puff, that I could grip & twist the mod, but that just twists the air intake closed during a puff.
So you hold & twist the middle part of the SP, which might be difficult to do without cruise mode, but the twisty-swirl method is only optional. I think you can get even vaping of your load without it, and perhaps a little stirring?
So I'm really encouraged by my SP at this point, and got pretty damn lit vaping only about 0.4-0.5g on it so far in 4 sessions? So I decide to up the ante with some mild concentrates
Mild in the sense that this is just some "volcano oil" as I call it. Just the condensation-scrapings that I recover from the inside of my volcano solid valve (and crafty cooling unit too) whenever I clean it. Been sitting in my jar for years, low-priority oil I don't care too much about, maybe only 40-50% thc with a little bit of dusty kiefy, vaped particles, but I "test vape / dab" this volcano oil at times, and it is still quite potent and tastes decent, with a shatter / pull snap consistency.
vape...piff...
man..the SP really shined with that little dot of oil on top
The flavor was still great with my old oil and tiny bed o' flower, I must have taken 20 puffs with a couple stirs to kill that bowl.
It came out pretty dark because of my volcano oil getting stirred around, but very even, far far from combusting. I ended my cruise at 410F and even the contrived, assy-end hits weren't that bad.
So this is just one day so far, but I'm strongly impressed with the Stempod so far! It's solid and well-machined, with a little heft. You might say it's a little big, with the glass stem perhaps, but it's not prohibitively large, and I can easily see this thing making it's way into my rotation. I don't have lots of other on-demand convection portables to compare it too, but the vapor strength & smoothness is at least comparable to the tubo evic.
and I'm not even pushing the limit 100% yet. There was slight harshness, but only on taking long, rapid, repeat draws, on the higher end of temps. Taste-wise? I think the glass & steel 'tubos' on funkyjunky's work might have a slight edge, flavor-wise, but it's really hard to say. I noticed only very slight metallic taste at the start, and couldn't notice it later. I'll look out for it, but maybe my coils just got broken-in and seasoned?
If I were to note some "down-sides" or other things: More regarding my mod & battery, I got "only" 2 bowls on a 70% full, old VTC5 at first, and I'm on track to get 4 bowls with a newer, fresh VTC5, which isn't all that great, but not horrible, and not an issue with an easy-cell swapping mod like a VTC/Vtwo mini. And for those that don't mind the heft, larger, 2 & 3 cell battery mods should match well with the SP.
Also, I was getting "device too hot" messages a couple times, somewhat easily, but I think if I don't let the device idle on cruise as much and get a better feel for it & practice, I can manage that better....
sooo....yea! w00t stempod!
Little reason to hold out on this if you're into 510 dry herb, full-convection, TC, open & adjustable air flow, adaptability & customizability! I think you've got a hit here, Dan.
Sigh.... I struggle to squeeze these posts in to under 10k characters, but usually fail too.
