ordering tips


1. The two terminals on the center post are the positive poles, and the negative poles are on the both sides of center post.

2. The users can install the NotchCoil with Cotton included in the package or roll the heating coil to their preference. Before rolling the coil, the users should unscrew the screws on the positive and negative poles with the equipped screwdriver. After completing rolling, screw the screws again and cut down the spare coils.

Note: While rolling the coil by users, the two slots on the atomizer base should be filled with cotton for delivering liquid.

3. Put the glass tube into the atomizer base tightly.

4. Put the airflow control ring on the regulating component and then put the top cap into the regulating component tightly.

Note: While adjusting the airflow, you should loosen the top cap and regulate the airflow control ring to the proper position. After adjusting, tighten the top cap again.

5. Put the mouthpiece into the top cap and the whole top cap component is assembled.

6. Drip some e-juice along the hole onto the atomizer base.

Note: The cotton should be saturated with e-liquid before using.

7. After filling, put the top cap component into the glass tube tightly and the whole atomizer is assembled.

These are fantastic little tanks, the airflow is unique, it's a little bit picky, but the versatility of this tank at 15w-40w is surprising. given the compact nature of the top airflow, it is a little bit restricted compared to the vandy vape pulse, so you can't run the coil as hot. It is a very well thought out, well executed tank, my only complaint is the lack of view port for juice on the stainless sleeve tank, but frankly I dig the exposed look of the thing, so not at all worried.

I ordered this tank on a whim after running across a review on Youtube. I love how different it looks from most other attys and when I saw the price I thought what the hell. It arrived in pristine condition and the authentication code worked fine. All of the pieces were very clean and everything fit together perfectly. The tank comes with a pre-installed coil that includes a wick that is roughly the size of a bail of cotton. I followed the advice of the many reviewers and trimmed the wick back so that it barely touches the base and so far so good. I find that sliding the included allen tool down between the cotton and the glass helps air flow and helps it wick more efficiently. The pre-installed notch coil is showing .203 ohms on my mod and I find that going over 60 watts is too much for the coil to keep up with and results in partially dry hits. I've went through a 5 tanks and for me 45-50 seems to be the sweet spot. I don't get as warm a vape as I normally like but the flavor is very good and the clouds are decent. A lot of folks have complained about the airflow being a pain in the ass to adjust and I guess if you someone who likes to change your airflow often it could be an issue. For me it's not a big deal. I tried several different variations and once I found one that worked I left it there. The only thing that I can say that I really disliked about the Theorem is the included glass drip tip. For me, it's much to small in diameter and it felt awkward to use. Also, vaping at at just 42W the small, narrow drip tip gets hot, fast. In order to vape you really have to purse your lips so as not to touch the metal top cap. This was easily fixed by simply switching to a different drip tip. Overall, I'm quite pleased with the Theorem. I bought it because it's different, looks cool, and will hold enough juice to get me through when I'm driving to and from work.

This little tank delivers flavor and clouds all day long. I'm vaping 100% VG and it wicks great. Like this in temp mode as well.

For someone using an RTA for the first time, it was pretty easy to figure out, even without looking at the instructions. It comes pre-installed with a coil and cotton. But after watching several videos, I learned that it is best to trim the ends of the cotton so it sits just shy of the bottom. I love that the tank is glass, and you can see everything going on inside. It is very easy to see when your juice is running low!
