I my opinion, the KFL is the easiest device to set up well to get great flavor from any juice. There is a bit of art to making a good micro coil, but once you get that down it's all butter from then on out.
To anyone having an issue with the coil build on a kayfun let me give this one piece of advice. Once you've wrapped the coil and torched it to hold it's shape (FYI, you can use a burner on a gas stove to heat the coil), let it cool down and then thread whatever you used to wrap it back into the coil. I use toothpicks, but use whatever you'd like.
Use this to keep the coil in shape and to make it easier to manipulate the coil as you're securing it to the deck.
so you heat the coil to get it closer together? and then what? lol
