Good question. I've got two Penelope v1s and love them, But the Odysseus kind of didn't do it for me. I really like the mellow Vape of the dualcoiled Ithaka. That said, I also own a Penny v3 and a kayfun, and said conversion Kit, and I prefere the kayfun-converted Odysseus to the original one and to the kayfun. I don't like to compare it to the Ithaka (for which I don't have the upgrade, but that's why I mentionned my penny v3 as I know and love the principle) because it just gives a different Vape I also like. The draw on the conversion kit is much airier then on the orginal Kay or Ody, which is why I like it and can give it a more brutal coil.
But I still use the Kayfun more on the road because it's less prone to leaking, more compact and has side-intake for air, so perfect for a minimal stealth 18350-mod.
In the end, I should probably shut my mouth as none of this is usefull information, me thinks...
If you love your pen v3, you will also love Ithaka. According to Imeo, Kayfun's core design is a copy of Ody/Ithaka.
Some of common issues with Kayfun
- tight draw. Ithaka has a huge draw and control it with AFC on GGTS/Just
- small juice channel can be easily blocked by wick. Ithaka has one of largest juice channel on the market
- if the coil gets too close to the deck, you can fry the plastic block insulator. Ithaka has no plastic on the deck
- you have to take the tank off the mod to refill which produces wear and tear on 510 thread. Ithaka is top fill. No need to dismount
- you need screw driver to refill. Ithaka top caps are thumb screwed
- if KFL+, center post isn't adjustable. (I had to grind the plastic ring to fit flush) Ithaka center post can be readjusted for flush mount
I am not bashing Kayfun. I actually love my Kayfun and think it is one of best atomizer on the market. Just that Ithaka is better.
