Kayfun & Russian versions nightmare. What are the differences?

[ForeverDiving]

The title says it all... At first I thought I understood the differences between a KF31 and a KFL, ditto Russian 100 vs 91. Now there are Kf31 ES, KFL plus, v2, v3, Russian v2, etc... Some clones even go to adding letters to the versions.

What gives? Can anybody break down the differences?

Much obliged!

There is one KF3.1 ES, KFL (Plus version is with air flow control) Russian 91% frankly like original derivative.
Other copies are...how is decided mfg or how they saw picture of atty or miss read some forum ;-)

Thanks Topper! I have an original Black Russian 91% on the way and my clones (bought to see if the type fit me without spending 130€!) are of decent quality. Actually, I found a KFL+ by Rainbow Heaven at a local B&M that is frankly perfect. I guess the only liberty the manufacturer took is with the AFC screw being an allen one using a 1.25mm key. However, since I glue them with loctite once I adjust them to my liking (wide open in ALL Kayfuns!) that's a moot point.

For me, I can't understood why clone mfgs continue to use this bad small screws on pots, but all of them still use theme !
Also and kids already know that the "magic" of kayfun-like attys is in base juice channels, but they continue to make it "how come that go".... and so on.
