The Kayfun 4 does have some pretty cool and unique features, but it does seem a little "over-engineered" in my opinion. I don't get why pbustardo raved about the fill method of the kayfun 4 but gave the lemo fill port a thumbs down becuase it was under the bottom 510 piece (for some reason non of the popular youtube reviewers including him mentioned that you can use the included o-rings instead of the screw to plug the fill port, if the screw was the only option I would kind of agree, but that o-ring makes things a thousand times easier). Having to screw and unscrew two different parts and closing off the air holes and then doing the same thing but in the opposite direction seems a little over complicated to me, taking your tank off the battery and unscrewing one bottom piece seems a lot easier to me, plus I think this set up is why the Lemo is almost leak proof. Don't get me wrong I love pbustardo's videos, he's probably my favorite youtube reviewer, I just didn't get this.
No more kayfun talk! This is the lemo thread haha.
Getting back on topic, I recently built a 1 ohm coil with 26 gauge kanthal on one of my Lemos and it is freaking serious. This is the lowest build I've done so far (1 ohm is the lowest resistance that will fire on my istick, so it's also the lowest that I could build) I was actually trying to get a 1.2-1.3 ohm reading, but the coil looked and work good so I decided to roll with it. I actually had to close the air flow a bit and I dropped my voltage wattage way down (3v/9w) because it was a too intense for my taste. Even at three volts the vapor production, throat hit, and flavor are off the charts. I don't know how people vape sub ohm coils at like 50 watts, that would kill me, I do use menthol liquids though, maybe if I was using a different flavor that wasn't as "in your face" as menthol I could crank it up more.
