It may have a legal thing to do with using the words “Kayfun” in the title; “KF” is the way they get around legal issues?

Depends on how you like to vape.
Modfather RTA 30MM
Titan Aromamizer
Voltrove 41MM
Wettest vape I’ve ever had in 8 years of vaping. The person next to me can taste it.
Am I doing it wrong?
Depends on what you like, set up as subjective as e-liquids i would say.

Yeah, that was my point. There’s something for everyone. It’s all good.
I heard a discussion about the same thing happening at Fasttech. Their Kayfun styled parts were suddenly gone, then a day or two later they were back as KF styled parts. I think you hit it on the head.
2Fdeal is where I’ve been getting clones and also authentics from China…and I find them excellent to order from, maybe its because they are a smaller company but customer service is top notch. That being said, I just received an Ulton clone of the Kayfun V5 squared, and am VERY happy with it. Its a larger (25mm) version of the Kayfun 5…with much larger airflow…I liked my kayfun 5 but this has much more airflow and it is a total pleasure to vape on. They also carry other kayfun version clones. That particular one is listed as the Ulton KF V5 316SS RTA 25mm. If you liked the Kayfun 5 but wished it had a tad more airflow, this fits the bill. It pleases me immensely. And only $22 ! Nicely finished and no leaks, threads and construction are very nice. Yep, 2Fdeal and Efun.top are probably my favorite chinese vendors these days.

Absolutely… I well remember my noob searches (and searches) for information.
3fvape still has the sxk kayfun 5 clone in the original 22mm 5ml, which is highly recommended but are sold out of the mini which i enjoy. extra cash for spare and i definitely grab one. The prime is more mtl then the v5. When u search, search KF seems there is something going on there like fasttech.

Biggest obvious difference is that one comes with a longer glass and chimney extension for 4ml. On a subtler level, one vape-chamber has an angled top while the other has a flat-top. No discernable difference in flavour I can tell.
Oh, and the 2/4ml version deck screws are complete rubbish - they eject wire rather than clamp it. I replaced them first build (from spares I got with other tanks) and I’m in love with these tanks!! MTL at it’s best 
Also - I’ve discovered I can get the same flavour out of the Kayfun Prime at 6.7W as I did from my Siren 22 and UTA2 at 8W (with the same coils 11-13 wrap 30G SS316L 2 Ohm 'ish contact). So less juice and more battery life

I bought a Kayfun 5 Mini and it was too loose to MTL, too tight to DL. So I throttled it (Google “DIY KF5 restrictor”) and it’s still too loose for a decent MTL. Forget it if you want anything close to a rollie or pipe draw…

I hurried to buy $15.33 ST Prime Styled RTA Rebuildable Tank Atomizer - 2ml / 304 stainless steel
and have the same problem:
As a result, the hooks near the screws are deformed and touched by the chimney.
The thread of topcap is very-very tight and has low quality.
Final decision: ONLY SXK or YFTK clones.
Funny - the screws on mine are fine, it’s the 2-4ml version with the crappy screws…
Same here if I open the juice control the full two turns. I’ve been experimenting and found 1 turn per 10W ie 3/4 turn for 7W, max VG. If I run 1 turn open at 7W by midday it gurgles…
For the Noobs here - and if it does gurgle, remove the drip tip, shake the tank out (like a thermometer), close the juice control completely, and keep it closed while you’re vaping until you detect a subtle change in the flavour, maybe the balance changes (you taste more of one flavour than previously), then open the juice control again. If you don’t open it at this point you’ll eventually get a dry hit. Go on, try it - enjoy ;p)

Can anyone tell me if the Prime wide open is similar to the K5 at 1 pip? I am not a MTL nor a DL type. I need just a touch more air than a" true" MTL and enjoy my K5s at the lowest setting.The listed air hole sizes would indicate that it is but those numbers don’t always translate.
I’m 99.99% sure the Kayfun 5 is still more airy at the smallest AFC setting than the Kayfun Prime is at the largest AFC setting. I have both but can’t actually do a valid check right now because I’ve throttled my K5. However I do recall that I could not MTL at all on the Kayfun 5, but I can MTL on the Kayfun Prime even at the largest AFC setting…
However I prefer the smallest setting.This MTL quest/journey from Siren to UTA2 to Kayfun 5 to Kayfun Prime has made me realise that I like to vape the same way I used to smoke a pipe or cigar. It would take several puffs (and corresponding application of lighted match) to get it going, tasting the changing flavours from ‘first-light’ to ‘çherry-glowing’, at which point I would inhale the lovely rich smoke. Which is why I run at 6.7W - after several puffs and power pulses it is as hot and rich as an 11W single draw vape, but I get to taste all the intermediate flavours on the way 
And at 6.7W, 4ml of juice and 1 x 18650 lasts 2 days Just to make sure I’m not deluded about the flavor - this setup is at least as flavoursome as my Bellus with twin Claptons at 60W, and my Serpent Mini with RipTripper’s setup at 24W. Nowhere near the clouds (or juice and battery consumption), but flavor and throat-hit are equal if not better.
You don’t need mega-watts for good flavor - the satisfaction is a bit like leaving the V8 at the lights in your well-tuned Datsun 1200 
(incidentally the UTA2 is easily as good as the Kayfun Prime, but the Prime has an easier build deck)

Lest we forget where vaping came from, and that even sub-ohming has only been around in wide circulation for a few years.
When I started vaping, there were still living threads where people were marveling at someone’s ability to build a deck with a ‘powerful’ 30w vape. So yes, certainly you don’t require high power for big flavor. I’m happy at 28w at the moment, and am always somewhere between 24w and 46w depending on the setup. I’m not one to knock anyone’s comfort zone (as long as you’re safe and understand what you’re doing), but there’s no doubt that after sub-ohm and high wattage became all the rage- with vendors gladly making them more and more powerful- it seems that you see so much “Power!! Go for the Power!!” that the lower power setups are almost portrayed as insufficient to new vapers. Far from true.
I was lulled by the siren song of the high watts when I started vaping, too, but have come to realize that the cell life and juice savings are just worth more to me than low builds and massive cumulonimbus clouds. And I get a great vape, which is really the whole point anyway.
Wow, I sound like a grumpy old man.

Update - I’ve lost the 2ml clone (and Pico!!), and the 2/4ml clone was randomly open-circuit, now permanently. New job, new unit, can’t find my multi-meter to fix it, and not sure I can be bothered as I’m happily back to using my UTA2 and field-mod Siren 22. Point is - the 2/4ml KF Prime clone is playing up… (please excuse the cumbersome spelling out for searches)

@CAAB … Moving this convo over to this old thread, since the subject matter leaned towards awesome vape flavor without having to build low ohm coils, coupled with vaping at high wattages. 
You asked why SS316 and not Kanthal wire?
A long while back, I thought I wanted to try temp control 
…thus, my purchase of SS316 wire. I found out I was not a fan of temp control; ‘nuff said. However, I did find out I liked SS316 as a vape wire; maybe a mental thing, but it between the SS wire and using rayon for wick, the flavor clarity of my liquids were outstandingly better than Kanthal and cotton. I decided to just stick with what I thought was better for me.
Why a 2.5mm ID coil?
With just about all of my 22mm RDAs and RTAs, a 2.5mm ID coil was as large as I could go before I risked a dead short against the housing of the atty. I’ve never moved too far away from a 22mm diameter atty; just prefer the size, due to most of my mods are around that size (single 18650, 18500 or 18350 batterys). I don’t need anything bigger for the way I vape.
