I love my Theorem...good thing I bought two while waiting on replacement glass from FT...FOURTH glass just broke within ~2 weeks of owning it.

I don't have any desire to contact Wismec over it...overall I'm happy with my tank, but if I were dependent on Theorems for my vapeocalypse stash I'd order about 200 replacement glass pieces.

Did I read it here (in this thread) that the FT clones of the Theorem might have thicker glass and that the replacement glass might be thicker, too? It's a shame...even the stainless steel sleeve was useless (plus very inconvenient to discern how much juice was left in the tank).

I have to give the Theorem a lot of points for effort, as when it's working, it is easily my best flavor/dense vapor performer (I do own several RDAs and subohm tanks, the Crown being my favorite tank). But I also expect to own an Avocado 24 or two next week. The single-coil option for simple builders like myself really makes a great Vape accessible.

I'm embarrassed to say that I'm still using my Theorem after I said I was gonna trash it. Since both my glass tanks went south, I have been using the SS and even though it's a PITA (and still a bit airy for me), it gives a damn good vape.

The SS is leaky for some reason. I didn't see any cracks, but it gets moist where the slits are. Also, if I remove it from my mod I see droplets of juice around my mod's 510. I haven't had any major leaks, however, I find myself having to wipe off the whole set-up a few times a day (and after every re-fill).

The slits are useless anyway...I have to hold it up to a light and rock it back and forth just to get an idea where the juice level is.

I hope they will iron out these kinks, but in the meantime, it's tiding me over nicely (if inconveniently) until my K5 arrives.

Mine is all washed, cleaned and put back in it's box. I am going to pif it to a friend.
Hopefully the Avocado 24 on they way will be much better.

Im actually not a fan of mine either. I much prefer my crown tank, or even the clieto over this. I have never really been a fan of drippers anyway, as I am always on the go. But I wanted to give this one a chance. I hate the notch coils, I keep getting burnt hits. I have even rewicked them to try and make them work better, and this is on somewhat thin juice. 70v/30p is my go to mix. The flavor also seems muted, and I even switched over to using clapton coils. I also find it somewhat hard to build on as the posts are fairly far apart. I duno, im sure im doing something wrong as there is nothing but good reviews on it. But I just dont care for it all too much.

Disappointed to hear the glass removal problems. Anyone find a way of doing this easily?

I dig in my thumbnail and run it around and it loosens right up for easy removal.

I'm brutal on equipment and haven't needed to use any of the two spare tanks that were included with mine.

I've read through a few pages of this thread and it seems nobody has tried just using the factory setup without cutting the wick which is what I did. The only draw back to not trimming the factory cotton is it seems to empty faster and needs refills often. I didn't even wash it out before using it and am noticing no machine oil taste.

I don't feel sorry for any of these fussy impatient people who refuse to spend a little time breaking something in before resorting to changing coils and wicks then .....ing about how it sucks

I'm enjoying this a lot, I wasn't sure it was going to be this good. Works great at different wattages

$22 well spent.

The only extra thing I did was use a micro screw driver once to improve the juice flow.

Chipped my first glass sleeve last night. I have been reading if people cracking them left and right and I silently laughed inside because I'm still on the first one. Karma hit me when I was taking it off to rewick while watching tv and it dinged the deck and took a little chunk off. No biggie.

I don't think there's any reason to get sanctimonious about it. The glass is noticeably and undeniably more fragile than most other tanks. I love the Theorem just the same, but pretending it's just the user's fault is internet posturing, not reality. Our goal should be to improve future iterations, not pretend the V1's flaws don't exist.

I got one of these today. Came along with my RX200S.

It's a strange little device for sure. The bottom tank design made me worry that it wouldn't wick well, but I've been using it all afternoon and it's working perfectly. I did snip the wicks down to just above the bottom of the tank, so it's not drowning in cotton like they ship it.

Mixed feelings about the notch coil so far. It tastes... antiseptic? at the moment. I'm curious to see how it breaks in.

My plan is to put a Clapton in it eventually. One thing I can say is that it could have benefited from a chuff tip. The little 510 it comes with is stubby and the heat sink gets VERY hot.

Follow up:

I fried my first coil by over driving it while messing with different mods. So I rebuilt it with the included spare notch coil and now it's really working great. Wicks fast, produces big clouds and gives pretty decent flavor, though it still has that cold, stainless edge to it. I'm getting excellent performance all the way down to 35w on it. I'm settling down somewhere around 40-45w.

I was wondering, like I say, I've been pretty happy with mine, but that's at 400deg and 35w, a little cooler.

Vaping it low works really well for sure. The notch coil seems to be able to produce a lot of pretty cool vapor right around 35w. I like a bit warmer cloud, so I'm coming down closer to 40w or so, which is warm but not hot.

Edit: Oh, forgot to say. I'm running mine with both AFC slots wide open.

I've got mine choked off, one air slot about 1/4 open over the coil. I've tried through the diverter, through the diverter and over the coil, on and on, the best flavor/throat hit I could find, for my tastes, was like mentioned. It's pretty warm like this, but I can do a semi MTL hit with it.

Makes sense. Less airflow.

I do MTL from time to time because I still have my ProVari Radius/Kabuki in the mix, but I've been moving more towards sub tanks and RDAs lately.

I'm trying, I've got a Dripbox, an Avocado on the way, a TFV4 and a few others to learn yet. I can do lung hits, but I sure enjoy sitting down with a KFL the most so far.
