I bought 2 Theorems and also have issues with 1 of them splitting glass. The first time the glass broke when my girlfriend tried taking it off to re wick. She left it for me to fix. Her replacement glass was crazy tight. Lubing the o rings helped slightly, but the glass broke as soon as I got it on.
Tried again with my spare glass, it lasted less than a day and split.
I've been wondering if the o rings are too thick. They seemed to have mashed down when I slid the sleeved glass on the problem child. I'm vaping it that way and gave the glass friendly one to my GF. Now I need a new TC mod to match the sleeve.
Problems aside, we are both enjoying these enough to consider buying 2 more.
Well, another update to the dog and pony show that is the PoS Theorem. I put the SS sleeved tank on after I broke the first tank. This evening I was going to install a 26g/36g fused Clapton and pulled the SS sleeve right off the glass trying to get the tank off again. No water required @sawlight, while I was pulling on it to get the tank free it started to slide and popped right off...
Another stupid design on the Theorem, the SS sleeve is razor sharp and sits down too far so it will easily cut into the top of your mod without tightening the atty down tight. If the sleeve was a smidgen higher so it wouldn't cut, you would not be able to hold onto the air ring while tightening the top cap.
If I had picked this up at a local B&M it would have been taken back for a full refund by now, but since it was not available locally and came from China, it is not worth the hassle or the wait.
There is light at the end of this dark tunnel though, and I do believe it will bring this steaming pile of stool back to useful status again. While I had the SS sleeve sitting on the table I decided to pull that glass tank off the atty. Taking about a half hour and working carefully not to crack this one, it finally came off in one piece. I dug through the parts box and pulled out a pair of 19x17x1mm Kayfun o-rings to replace the Green Gummy Bear's on the Theorem. Put the tank back on and it has a good stiff hold without being too tight or falling off. If you did hold it by the glass with a mod attached and gave it a flick downward, it would pull free of the base. The friction on those o-rings will be perfectly acceptable for daily use IMHO. If someone has some 1.2mm o-rings to try they would be a little tighter. I changed the top cap o-ring as well so its all matchy matchy, it is a little loose with only one o-ring, so I will try out a few thicker ones.
Give it a try and see how it works out, it's nice to be able to remove the tank like ever other glass compression held tank.
Threads like these will frustrate you more than solve any problems. For every person that has had the tank break just getting it off the base, WITHOUT any previous trauma to the atty or janking it off sideways etc. There will be 10 who have never had a problem and will blame you for the problem you are having.

Just have a look in the eVic VTC Mini thread when we were all trying to get TC working properly on it, threads were even created on Joyetech's site detailing the issues. The forums there are filled with staff and shills who don't have any solution to the problem, because there isn't any solution... The big Chinese manufacturers do not read ECF, they just take notes from your emails on how to make the next SKU in production more profitable.
The same thing with the Theorem. Replace the base o-rings with 19x17x1mm and the glass will work as it should, I have had the tank off and on 10 times without any concern for the possibility of a broken tank. This is an easy fix and if they do ship you a replacement tank or two, then it's all good! The metal sleeve is poorly designed and stupidly implemented, that must have been Matt from SMM's input.
I'll put a little PC-11 around the inside top of the sleeve and slide it onto the glass, putting it at the proper height, so it will not score the top of my mod from being down too far like it was.
My only issue now is filling this little pig, MaxVG from a 30ml PTFE juice bottle will sometimes just not go down that fill hole.
For future reference, if it says Joyetech or Wismec then by all means give it a pass.
you will get the Wismec/Joyetech Fanboys up in arms
Fortunately I didn't get it for vapor production, I got it for a flavor machine, and in that aspect, I am VERY happy with it. It comes right through with the flavor.
Glad it wasn't just me on that one! It's workable in that aspect, but an over sight none the less.
I don't have the Theorum, but I saw several post about the glass problem, so never considered getting one. It doesn't help that my replacement RX200 that I received 2 weeks ago because the 1st one was overheating, is now having problems with just shutting off for no reason and won't stay on. I'm troubleshooting it now, but it may be returned and replaced with something else not Wismec/JoyetechThreads like these will frustrate you more than solve any problems.

Are you sure you haven't dropped or abused it? I haven't had that problem, or heard about it, so it's a non-issue to me!
Maybe it's just my imagination because this is the greatest Mod ever made.
