I’m a Kayfun guy. For my buck, it’s the best performing tank out there. One you learn how to wick it, it just works. Consistently and reliably. It is, however, not without its flaws. And I’m always on the look out of something that will perform as well, but address some of the issues the Kayfun system has. So when I saw the specs on the Lemo 2 by Eleaf, my first thought was: This is what Kayfun V3 should have been! On paper it flawlessly address 3 of the 4 major issues that I and most people had with the Kayfuns. Those being:
1. Screw to fill.
2. Screw(s) to adjust airflow
3. insufficient airflow for lung-hitters
The AFC ring on the Lemo 2 is where one would expect AFC rings to be: on the bottom of the tank and easily adjustable. As an aside, I can’t belive the Kayfun V4 still features a screw on the bottom to do this. Anyway, back to the Lemo 2. The fill-port is on the side at the very top, and if one actually follows instructions and fills it while keeping the tank horizontal, the process is clean, simple and leak-free. And the 7mm chimney with dual 1cm openings provide more than enough air-flow to lung hit it. The only ‘issue’ that remains is is that it still needs to be drained to get to the coil. Draining it, however, is also a breeze. Simply reverse the filling instructions: Open the air-flow, open the fill-port and tilt. Voila!
Lemo 2 is advertised as a sub-ohm RTA – like everything else these days – and having played with it in that configuration it definitely delivers. It’s got more than sufficient airflow for a single coil tank; large, easy to work with build deck; and massive peek insulators to handle the heat. Out of the gate I loaded it up with some Dis Funk-tional family e-liquid (70%VG) from Create A Cig and hit it at about 35 Watts. For those of you who are wondering, I used a kanger subox for this test, but the lemo 2 can be paired with all good box mods. 35 Watts was bit too much, as it turned out. However, It worked flawlessly at about 30 and my sweet-spot was 25. Remember, folks, it’s a single coil. It put out good amount of vapor and had very good flavor.
But I got this tank for different purposes. I wanted to see if it can replace my trusty Kayfun 3.1s. I put a 1.2 ohm, 26ga 2.4mm coil on it, wicked it, filled it and closed off the airflow to about 90% of the way – I’m a mouth-to-lunger so I like a reasonably tight draw. Apply 16 Watts of power and…. not bad! Despite the large chamber and wide chimney, I can not notice any significant flavor degradation when comparing it to Kayfun V3 and V4. I did end up replacing the 12mm drip-tip with something far more reasonable. I’ll gladly fellate my Dark Horse RDA all day long, but I like a much more reasonable mouth piece on my tanks.
This tank is not without its flaws, however. The airflow is not all that gradual. I see no difference between 30% open and 100% open. If you’re trying to set up a good mouth-to-lung hit, we’re talking about making minute adjustments – too minute. The o-rings from the top and bottom of the glass do not stay in place when the tank is disassembled. They are whitish/clearish and very easy to lose, so be careful when working with it. Also, if you’re not careful when assembling the tank, the bottom o-ring likes to raise up and block the juice channels. It’s very easy to avoid, but something one must pay attention to. Finally, I would like to be able to disassemble the top-cap for cleaning.
Over all it’s a great and versatile tank. Between good performance, convenience of operation, the glass tube and very wide range of supported builds it’s very hard not to like it. And if you’re one of those who loves the Kayfun accept for the airflow, give this tank a go. I think you’ll like it.
