The overall design of the nunchuk is comfortable and easy to use. I like that it's wire is long enough to place out of the way and doesn't interfere with my activity. I have used this product with my wii fit and with the EA Sport Active with the nunchuk strap. During the boxing portions or things when I am actually holding the device it works really well. But on the SA portion because it is lower and "strapped" to my leg I kept receiving an error and the games kept pausing. I am not sure if this is a nunchuk thing or an EA thing but it was really annoying.
