The disc drive on my wii started making ominous sounds, and one of our games was scratched so it wouldn't play. I called Nintendo about it, and they immediately sent me a shipping label. I packed up my Wii with promises of it being returned within 12 business days, the family was distraught, that is a long time without Animal crossing, but joy was restored when just two days later the Wii returned, all fixed, and with a replacement disc to boot.
I agree, the service was excellent indeed.
