The kit includes three tubes which are inserted from above into the center post to restrict the airflow.

  1. Rated 5 out of 5

    5 star to the mtl kit works great. 5 stars to origin vape as well thank you.

  2. Rated 5 out of 5

    This MTL completes the kayfun 5 which to me is the best rta I have ever bought. There really is something to you get what you pay for. Origin vape is as well 5 star operation.

  3. Rated 5 out of 5

    As a long time user of authentic KFL+ V2, V4 and Mini V3, these reducers should have been included in the kit. But since they weren’t, yes they are worth the price. Interestingly, they fit and properly seat in the SXK Kayfun V5 Mini.

  4. on all the chinese clones, sometimes they do, sometimes they don’t

  5. Rated 4 out of 5

    These work as advertised and make the Kayfun V5 more MTL compatible. I like the smallest 1.2 mm the best but the 1.4 mm is not much different. I do not use the 1.6 mm so I had to get a couple sets to cover my multiple Kayfuns. These should be included with the atty IMO.

  6. Rated 5 out of 5

    I was using my Kayfun V5 less and less, mainly using my Pico instead. I started having buyers remorse, because I’m not a direct lung Vaper anymore. Shockingly, I can’t put it down now. Definitely worth $10

  7. If it is a 1:1

  8. Does this fit the SJMY Kayfun v5?

  9. Rated 4 out of 5

    I am using the smallest one and the airflow on the “2 notches” …works wonderfully, better than the K3 mini. And I can add or remove airflow now without having to get a mini screwdriver and try to adjust the airflow (like in the K3 mini). I would give it 5, but it really should just be included with the K5 to begin with, so I give it 4. Origin Vape, well… I give them eleven stars.

  10. Rated 5 out of 5

    I use the middle one and it works fine.

  11. I’m used to a 0.9mm airflow … What kind of an airflow can I expect with a 1.2 mm center plug and a 1.8mm bottom airflow setting ?

  12. Rated 4 out of 5

    My first Kayfun product was the mini V3, I had previously used the Taifun GT2, and was blown away by the design, construction, and flavor of the mini V3. I finally got the Kayfun 5 and was a little disappointed. I feel like the 5 is just a high-end Lemo 2 with the loose draw and large chamber. These inserts fit nicely and improve the draw if you prefer a tight draw.

  13. Rated 5 out of 5

    The products are as advertised. I am still working on “dialing in” the same vape experience (I’m a flavor person) I receive on the KF4 or KFmini. So far, the largest hole size insert and the KF5 at 3 or 4 ticks seems best for flavor, but to me not exactly the same as either of the other KF tanks I own.

  14. Rated 5 out of 5

    If you enjoy a MTL vape this kit is a must. With the largest tube fitted I am now getting an even better vape than I do with my Kayfun mini v3 and that says a lot. The versatility I now have with this set up is amazing.

  15. Rated 5 out of 5

    First, I’ve never owned a previous Kayfun, so I cannot compare this with the airflow of the previous models. That said, I’m really enjoying the 1.6mm, which is the largest insert and I’m most likely just going to leave it in there. You can still use the 4 adjustable airflow settings to get a different experience, and I am now preferring wide open with the insert (4 pips).
