  • (1) KFL Atomizer Clone (with stainless center tank section)
  • (1) “Makrolon” clear tank section (polycarbonate)
  • (1) Kayfun style drip tip
  • (1) Short style drip tip
  • (1) Padded travel/storage box
  • (1) Mini keychain screwdriver
  • (1) Small piece of silica wick
  • (1) small piece of kanthal wire (unspecified gauge)
  • (4) Large o-rings (for the tank sections)
  • (2) Small o-rings (for the 510 drip tip socket)
  • (2) Spare post screws


  • Relatively low cost.
  • Decent example of a KFL style atomizer.
  • Comes with everything a real KFL comes with.
  • “Standard” 510 drip tip socket.


  • Extremely difficult to disassemble (very tight tolerances, and o-rings, no texture to grip.
  • Fit and finish is off from the actual KFL by a wide margin.
  • Non adjustable tight draw (relatively speaking).


I ordered this from eciggity on a lark, having never owned a Kayfun style atomizer. My intent was to decide if I might want to spend the money on a real KFL+, so I ordered the EHPRO KFL+ clone, and they sent the KFL clone. I don’t know what I expected.

This is more of an imitation than a clone, it does not have any of the actual Kayfun markings, but is clearly intended to copy the design.

The flavor on this atomizer is stellar. Unbelievable. I will absolutely be ordering a legit KFL+ (as soon as I can find it in stock somewhere).

The sheer quantity of stuff included in the package is surprising. I did not expect all of that with a clone.

Fit and Finish

You can see in this picture that EHPRO missed the chamfer on the top tank section:

Everything on this clone is very smooth, which coupled with the very tight fit makes this thing an absolute bear to disassemble. I suppose this is good, as the tank seal is absolutely airtight.

The draw

My only real complaint is that the non adjustable draw on this tank is very much tighter than I like (I prefer an airy draw), but if that is the price for the absolutely wonderful flavor, I am willing to pay it gladly. As I mentioned, I will be buying a legit KFL+ as soon as I can find one in stock, and am hoping that the adjustable airflow will get me closer to where I want to be.

I will note here that I build this with a vertical micro coil centered over the air hole, wrapped with sterile cotton around the outside of the coil.

Minor leaking, occasionally

I’m not gonna mince words here, I experienced leaking from the fill screw on the bottom of the unit. Not every time, not with any reason I could figure out. Sometimes it just leaked. This could be from taking it outside in ~30F temperatures, and then indoors into ~70F temperatures (though it was not consistent), or it could be a design flaw. Not sure. This leak wasn’t terribly bad, it was just annoying.

I did on two occasions experience leaking from the air hole in the side of the unit. I don’t know what that is about. Again, could be from environmental changes, hell it might even be from the way I was drawing on the thing (it is a bottom coil unit, and I was drawing on it pretty hard).

I am hoping that the leaking is just an artifact of it being a clone.


For completeness I am going to talk a wee bit about assembling the Kayfun style atomizers. All things considered, there are quite a number of parts to these things. If you’re not familiar (or not mechanically inclined) you might get into trouble figuring out how to get the thing back together. Here are all of the parts, lined up in assembly order (sorry about the poor lighting):

This is basically what you want to do after getting the coil built and wicked as you prefer (the first pic shows the atomizer deck with the chimney base attached):

You could fully assemble the chimney, and then mount it on the atomizer deck, but I prefer being able to see the coil and verify that nothing is touching before closing it up.

At this point it doesn’t matter which tank section you use, as long as you use either the top or the bottom (no male threads, only the center section has male threads) because those two pieces are threaded the same.

This clone is debatably worth the $49.99 that I paid for it. It is far from the best Kayfun clone I’ve seen, but it is not bad either. The flavor production is excellent. It did in fact accomplish what I wanted. I have decided to buy a real Kayfun without having to buy a Kayfun and then discovering that I don’t like it, but I can’t say I would recommend this to someone who was planning on using it as a daily driver.



One thought on “Hardware Review: EHPRO Kayfun Lite Clone

  1. Good review, I have the ehpro as well as tabeco clone kayfun and I feel exactly the same way. Draw is too hard, and it leaks from the air hole when you least expect it to. The tabeco is actually better functioning with adjustable air, but it clogged the air hole on me after every two or three weeks and needed a full tear down and good soaking in hot water and vinegar to get it clean inside the air hole.
