That Theorem

I got it… The notch coils ite but some thicker walled options would be better. Not much past 55w but burnt wicking. Not into tc so… Meh… Disheartened I remembered hearing something about dual verticals and laced it up with two 34 x 2x26 fused with 5 wraps on 3mm reading .24 and lemme tell you… They did not disappoint. Spits some at higher wattage wicks easily… Air flows nice from the back out of the reducer. I don’t use the top one much. Flavors great. 3 ml capacity… For a lower profile rda look I suppose. Plenty o goodies…2 extra tank glass one shielded. Complaints= juice hole is tricky if not using a dropper and the top cap it difficult all the way around. Removing and adjusting airflow is a pain. Heat with the drip tip provided is an issue if you vape hotter. but over all a good buy on my end but I tried that griffin and I’m get one too.

Yeah, from what I read, unless you do TC with the notch coils, it can be the WORST dry hit of your life as they ramp up VERY fast!!! Heard no one really likes the adjustable airflow is only adjustable with some disassemble required…

That’s looks like it will hit like a truck with flavor for miles. Nice

Well I’ve heard both ways with the notch coils. If they ramp up that fast and that hot then you don’t need lots of power. Should be awesome flavor at lower watts with longer battery life. Ok I’m done rambling lol :scream:

I agree with your assessment of the notched coil- only worked for me in temp control. In power mode, I got that metallic taste from the nickel leads. In temp control, the vape was okay, not great. I rebuilt it with a stainless single coil, and it’s great on flavor. One annoyance I found is I have to fill it often, and the fill hole is recessed enough that you have to use a dropper- my plastic needle bottles cannot be used to fill it. And I wish they provided o-rings in other colors.

If you get one of these, don’t use the cotton provided. I changed mine out immediately, and there was a ring of machine oil where the notched coil was. So glad I didn’t vape that!

Just tried out the Theorem for the first time. I didn’t use the notch coil but wrapped a 316L ss 3mm interior diameter 4.5 wrap 28g at about .56ohm at a first test on it. I have the single air flow ring in (and it’s still pretty breezy). I had a terrible time getting the thin wire coil to line up in the tank, one leg is pretty long, but it has a nice vape to it.

Nice, I think I’ll try that set up next go…

Okay, I’m having the worst kind of time removing the glass tank from the build deck of the Theorem. I push and pull and fight with it every time. In the videos I’ve seen, the people just seem to be able to push the deck out without a problem… is there a trick I’m missing or does it get easier/looser over time?

Yea, put some eliquid on the o ring before you put the glass on. I broke 2 pulling them off. They wanted to make sure that thing didn’t leak…

@Beaufort_Batches agreed. Especially if you’re cleaning between builds in an ultrasonic. It can get too clean and glass and silicone like to bond when dry (and metal and rubber)

Thanks, I will do that the next time I break down the tank.

weighing in on this one a bit late… but the Theorem is 5*+ for me… I’ve had mine for a little over 3 weeks now… used the notched coil for a week until i melted it. it’s not recommended over 50w so I guess it was that time i hit it a few times over 70w in my Cloupor GT 80w TC :nerd::laughing: but was great flavour and reasonable ramp up at 30w > 33w. at the moment running a single 6 wrap, 3mm, twisted 28g SS coil @ 0.65 ohms and the flavour is fantastic.

yes, it’s a bitch to fuel up unless your using a glass dropper or pipette … and yes, the top cap can be a struggle to get off… and yes, the glass can be a real prick to release from the deck (I just run a little VG around the 2 o-rings now) and yes, the airflow setup is a little finicky to set… but overall the pros, IMHO, far outweigh the few cons on this RDTA. plenty of air if needed, no leaks, quality o-rings and construction and a nice tasty warm vape at 30w > 35w and chucks a decent cloud. A little limited on builds for it… you can’t build too low or the tank gets pretty hot but where it is is where i want to be … just a warm, flavourful and very satisfying vape.

I have the Griffin 25, Troll, Limitless plus, Sapor RDTA, Velocity Mini, Velocity V2, 3 Kennedy clones, Plume Veil clone, Sigelei Moonshot V2 and a Snapdragon clone but the Theorem is definitely my new go-to tank and have just ordered another and sorry I didn’t get a third. Looking forward to a V2 version with a few of the design issues sorted and maybe a little larger juice capacity.

:+1::+1: double thumbs up for me :yum::nerd:
