Attack of the (Kayfun v4) Clones!

[Boden]

Not sure about well regarded but FT has them.

$25.84 Infinite Kayfun V4 Styled RTA Rebuildable Tank Atomizer - stainless steel / 23.2mm diameter at FastTech - Worldwide Free Shipping

Personally, I'd recommend the Tobeco. Excellent copy, cheaper and ships from US.
Kayfun V4 Clone by Tobeco
Code: 5off

Thanks,
Any other single coil rta's that you would recommend. I've been out of the country for the past two years and would like to pick up some new toys. I don't like dual coil and sifting through all the options is making me a bit weary.

Thanks again,
Boden

Edit: A friend gave me two Russian 91% V2's I like

The Infinite is well made and looks great but that bell cap requires you to fill it from the bottom with a syringe. If it had a top fill option then that would be the bell cap I'd put on every device it would fit on.

Actually it doesn't! I use mine all the time - you just take of the drip tip, plug the top with that little doohickey that comes with the Infinite, take the whole bell cap off the chimney and fill it right up. You can just pour from a bottle

I was wondering what that little plug was for!
Doesn't the juice go up the chimney part way as well? Just let it drain out back into the bottle after you screw the bell cap on?

I suppose a tiny bit of juice goes into the chimney when you insert it back in the bell cap, but it's negligible. I just turn the wattage up to about 30 watts to burn it off and then turn it back down to my regular 20. I love this bell cap, so much so I ordered some more from FT! The best thing really is that you're free from the annoying opening and closing of the juice flow - you can just leave it open all the time. However, be warned, I left mine on its side today and it did leak!

Thanks for the great info!
I will try this out and see how it works!

 

[AmandaD]

Let me know how it works out!

If you like the Russian 91%, you'll love the KF v4. The Lemo 2 has more air flow. I have 7 KF v4's and 4 KFL+'s. I'm only using KF v4's now. I have a few drippers but only use them for tasting new juices or if I feel like blowing clouds.

*edit*
Definitely watch some youtube videos on the KFv4.

 

[DaveP]

I've seen many who like the free flow air in the K4, but I'm one who likes a little back pressure that simulates a filter tip. I don't care to lung inhale, so free air flow isn't on my list.

I'm finding myself picking up the EHPRO KV3 more often these days just because of that. I swap back and forth between the Tobecco KV4 and the EHpro KV3 and I like some aspects of both depending on my mood, though.

Have you tried closing off the airflow on the KF4 clone? I can back my tobeco down to almost no airflow.

 

[KTMRider]

It took about a day to get used to the air flow of the KFv4. I like it much better that my KFL+'s now. And no more whistling!!!

 

[juicynoos]

With the EHpro KV4 I guess that "Eco friendly Stainless Steel" is also heat friendly!

This problem is strange
The Ehpro is completely different to the tobeco
First I opened the air flow all the way open still heated up and started dry hits after 3 or 4 long hits
So went to wicking had to stuff Japanese cotton into the coil and cut it to just barely above the deck
Over heating and dry hits stopped
Now it works fine

Thanks dave51 for that info. since I just received the 'updated' version to check out!

 

[dave51]

Another thing Ive noticed
Just looking at the $9 Tobeco kafun 4s I have and the Ehpro seems like the Ehpro is smaller in diameter than the kayfuns
Someone with a good set of calipers might check

The $9 Tobeco seems to be larger in diameter than the first run Tobeco Kayfun 4 I have

It may be an optical illusion but seems that way to me

 

[cobalt327]

All my KFv4s are 22mm, inc. the ones from Vapor Range.

 

[dave51]

The Vapor Range Kayfun4s all look the same
But i have a first run Tobeco Kayfun 4 from another shop that looks smaller it could be an optical illusion
i dont have calipers to check

You don't need calipers; you just need to swap tanks.

 

[dave51]

dont need to swap tanks they all have the glass tank installed
I was just making an observation about the differences in size

 

[cobalt327]

The KFv4 that I have that's not from VR was from GB, don't know the maker. The thing is, a lot of work and trouble would need to be expended to change the diameter- right up to different glass sections, etc. That would also mean none of the replacement bases or glass/metal tanks or bellcap assemblies would fit correctly. Not saying you're not seeing what you think you're seeing, just that it's likely to be an optical illusion.

 

[doofy666]

Sure, but if you put tank 'a' onto base 'b' you determine if there's a size difference.

I see what you are saying
Th Ehpro and the first run Kayfun4 that look smaller are the only ones gave me any kind of problem

FT has a 28mm (or is it 30mm) K4.
