Just received a Kayfun V5 today from Origin, and this is the best Kayfun experience I have had.
Little history hoping this helps someone. I had started out a couple years ago with the Kayfun Lite on my Provari 2.5. I am grateful to that device for teaching me the basics on how to build. Unfortunately I was not good at it. I was always getting dry hits and leaks, never got that full Kayfun flavor, and eventually gave up and sold it. I tried the Kayfun Lite Plus and a Russian 91 and just could not get it right. I live in NJ and there were maybe 5 shops in the state at the time, so I counted on Youtube to teach me. I built a nice coil, but my wicking was always wrong. I sold those both. One day a new shop opened up. When talking with owner I explained my constant problems, I discovered that using cotton balls for wicks from my local pharmacy was probably the biggest problem, and a horrible idea.
Then the Kayfun 4 released. When that came out I decided to try it again after reading the excellent reviews. I had gotten better with my builds, got better taste....THIS time I used Japanese cotton but I kept having leaking issues. I gave it a month, enjoyed the flavor, but it was a complicated device to use....once again I gave up and sold it.
Since then I got into dripping, I was determined to learn how to do this right. I really wanted to find that great flavor build. I posted on the forums for suggestions and finally a very patient vape shop guy walked me through doing it right. I learned my biggest problem was I was too thin on the cotton in the coil, while packing in a bit too much in the well. I can finally get incredible taste from my dripper. I drip at home and have been using my Provari Radius and Kabuki all day for MTL which I prefer.
The Kayfun V5 released and I waited a couple months this time. I ordered it Sunday Night after reading through this thread and watching enough reviews on Youtube. I received it today along with the MTL kit. I opened it up and cleaned everything up. I went to the store before I got home to pick up some VG to lubricate the two O Rings as suggested by Svoe Mesto website. I installed the largest piece from the MTL kit, built using 26 Gauge Kanthal 7 wraps on a 3mm bit. I am getting 1 ohm reading, popped it on my Radius and worked the wattage to 15 and using boost 3. I filled it with some Philip Rock Creme de la Creme, and this flavor is incredible. I am so happy I finally seem to have gotten this right. I am only 6 hours in mind you, and I think I will be keeping my Kabuki close as I test this out for a couple weeks to confirm no leaks or dry hits. I appreciate the size of the deck, building was simple. I also like the size of the tank for extra juice. The MTL kit allowed me to dial in the perfect draw. If this experience continues to go this great, this tank will be my new go to. This flavor is so good. I want to thank you guys for the terrific information throughout, it helped make up my mind.
