This is the drip tip mouthpiece I'm currently using on my KF Mini V3s. Because otherwise the regular SS kayfun drip tips just run too warm for comfortable chain vaping. This makes a big difference, as I can run at higher watts, with a higher top temp limit in TC mode, than I otherwise would be able to - and yet do so more comfortably. On the other hand, this drip tip (of which I have several of the same exact one, from FT) fits a little looser (only one o-ring), and sits taller in the tank, than I would prefer. There are very few alternate drip tips that'll fit a KF Mini V3, and also work well (at least for this purpose), so this setup is not bad. I just wish it was more perfect. A lower profile drip tip that fit tighter would look nicer, yet also allow for easier screwing off of the top fill cap. With the one pictured below, I have to pop the drip tip out every time I refill, then unscrew the top cap - which is much harder to grip well without that really tight fitting KF drip tip in there to grab onto. On the other hand, the heat insulating characteristics of the below drip tip are really nice, as is the feel between my lips - though visually the setup certainly does look more awkward than I'd prefer.
