Looks interesting. Giving it a spin and it is definitely simple and fast. Since I'm coming from the Google Launcher I'm not used to anything fancy, so maybe I'll stick with this for a while. I tried to use Nokia's Z Launcher for a while but couldn't get used to the gesture search.
I just wish it didn't cover my wallpaper, but apparently they are working on transparency. I use the "Google Now Launcher" as well. Going to give KISS a spin for a few days, but don't think it will stick.
