Plenty of people have commented in the mini Kayfun thread that they are getting a better vape with the mini compared to their full sized Kayfun. So you're in good company
I have the Tobeco version and its a great vape too. I paid as much for it as the Ivogo version. Wish I'd gotten the Ivogo because I can't use the clear tank section in the standard 2 section setup because its the same diameter as the metal tank sections although it works fine as the middle section in the long configuration. I use 50/50 and higher VG juices, a few people have said it works for them but I'm guessing they're using 100% PG juice.
glad to know i'm not the only one enjoying this atty, swimming against fashion wider current..
i'm using 80vg/10pg/10water, the bubbles move very very slow, but haven't got dry issues yet. thx for the info!
Funny that you just got the iVOGO Kayfun Mini, I actually did a review of it, and its posted, but the owner of the site has scheduled it to publish on 8/14

Why, I am not sure? The Kayfun Mini is a high demand item right now, so it would make sense to me to publish it now, but whatever *shrugs* I was initially thinking of the 14500 Nemmy for the KF mini, but I am actually leaning towards the Ego Mega 1200mah VV for it. But I also enjoy it on the DNA30 too.
i knew you were going to review it. when i saw the mini kf in the instant kill, remembered your comments about it, and decided to try. it's 14mm, like our ego batteries (mini nemi is 17mm), my first buys in fc included two 1100mAh batteries, which were unused in the shelf. so i'm using them. but it's been so good vaping, that decided to instant kill the mini nemi (stock was 20 units!), and ordered a sticker in ft (this way, the 5ml mode is more usable).
lol, this thread is a "commitment" but hopefully folks will understand that I am haven't been around quite as much as I am used to, I am plenty busy these days with a fair amount of stuff in my review que as P.Busardo would say.
we all know you are work is increasing everyday, so we won't blame on you if you sometimes don't drop by. note "sometimes" word, hehe.
Wow, you ordered 6 of those spare tubes eh? Haku I get the sense that you are a man who likes to be prepared for everything ;-)
lol, remember i'm tauro. and also remember that the 4nine has also M20x0.5 threads (so the 21mm tube, instead of the 19mm one, can help if you have tight space for button top batteries, as is my case with a true 49mm 4nine)

although they are 4mm tall, so 1mm of thread will be showed.
you are right, i could had bought already the fc sxk sr x, if i had not bought so many magnets and o-rings.
btw, 10x8x2 magnets don't improve the vela switch. maybe if they were 1.5mm thick.. but didn't find 1.5mm magnets. anyway, the switch becomes more clicky, less smooth than with the spring.
now i'm trying to guess and order all the o-rings needed for my different 5 kayfuns. planning to replace main 20x1 orings with 13x1.5, or 16x1.5 (middle section), and to have the perfect silicone replacements for the top cap groove orings, which are essential to eliminate leaking; they go from 7.5 to 9mm OD, and from 1.5 to 2mm thickness, depending of the specific kayfun model.
btw, i've received the $12 kayfun. no accessories, no groove o-ring, this is perfect. the base is very similar to the tobeco wide squared channels version (channels are even wider here). the chamber is 13mm tall, but the chimney has thinner walls, and it reaches the cap groove easily (good seal). the look (kind of brushed..) reminds me tobeco version as well.
but couldn't use its 510 pin for my kfl v2 base. this has 3.2mm diameter, while v2 uses 3mm wide pin. it doesn't fit, and didn't want to force it. will try the $17 one instead.
