As I said, the Nunchuk fits comfortably in your hand, the control is great and the Z and C button can be detected without difficulty both.
The range is very large, theoretically I could even sit in the next room and try a figure to Also check.
Also quite positive, the Nunchuk can not accidentally pull out of the Remote when this moves too hectic.
More really can be to not say, except that video games quickly cope even people new to it.
