Kfl or kfl+? + has a air adjustment screw. Even with the screw it feels like a tight draw.
If you have the tifun, don't waste your time with the fogger. I got fogger because I couldn't afford tifun. Fogger is tifun style, but harder to build.
I think the kfl+ is super easy to build, and I've never had leaking, until I take the cap off and forget to cover the air hole....
Fogger v3 leaks like no other if you don't have the channels PACKED with cotton. It came with a wire mesh build. I never tried it, but I will eventually... With the fogger channels PACKED with cotton, I have had no leaking issues. Left the air adjustment wide open all night, and still no problems. You need to play with the air flow a bit to avoid gurgling, but I still like it. Would prefer tifun I think... If I could afford it.
Fogger preforms awesome when you get the build right, and set the air adjustment correctly, better than kfl+ I think. But kfl+ isn't as finicky with the build in my experience. You can do a mediocre build and not have catastrophic leaking...
