I bought a Nyko charge station for my Wii about 6 months ago... (Charger stand, two batteries, and rubberized backs). It is a great little device and keeps the wiimotes charged and ready to go. It is one of the best accessories I've purchased. For some reason, the base stopped charging about a month ago. I was disappointed as I figured 30 bucks was down the drain....
I emailed Nyko and got a very friendly email back with shipping instructions to return it. I only sent the base in and kept the battery packs and backs as I didn't figure they wanted those. I sent it in about a week ago and today, via DHL overnight, they sent me a brand new retail pack. What's so cool is that I now have spare batteries and backs for my other wiimotes. That wasn't my intention, but it was cool of them to send me a full retail package given what I sent in.
I don't generally make these kinds of posts, but that, sir, is good customer service, and Nyko deserves a +1.
