Hello everyone. When I first got this product and installed it, I right away noticed a difference in flavor. You have to first understand, I vape only STRAIGHT menthol. No peppermint flavor or anything else, just 4 ingredients, PG, VG, nicotine and menthol. So when I say flavor I mean cleanliness of taste, lack of burnt taste, and smoothness, without too much of a sharpness. This pin wasn't much different than the standard one, but it did make everything a bit smoother, bit better experience.

Secondly, it is a tighter draw, but I was using the original pin on a tight draw anyways, and I use my Kayfun Prime on either 1.0 or 1.2mm so I prefer a very tight draw. I just tested this pin with the bottom screw only backed off half a turn from closed, and it still vaped well, though extremely tight. This tight was not possible with the original pin!

Lastly, with the first pin, that had no hole in the middle, if you turned it in all the way the tank was 100% completely closed. Just like taking a Kayfun Prime and turning juice flow control to closed. With this pin, it feels like ~96% closed. There is still airflow due to the hole in the middle of the pin. So you can close it almost always, but for 100%. How often will this matter? almost never since the Kayfun Lite Plus almost NEVER leaks, but if your going to store a full tank for months, maybe don't store it full...

All in all, if you prefer better flavor, more even airflow across your coil, and a tighter draw, this is a MUST GET assessory for you Kayfun Lite Plus. Your already spending over $120 on the tank, what's an extra $10 for this amazing pin>
