The only thing i don't like about the temprature sensitive one is that you can't control the color of the leds, temprature does. So unless you change the temp of the wii the color is whatever it wants to be. The chance of seeing it go red is pretty rare as Wii doesn't seem to have any overheating problems. not in my expirience at least. i'll end up getting the one where you manually change the colors.
