I bought my Cardiosport GT3 Heart Rate Monitor Watch back in 2008. Recently one the wristband pin popped out and managed to strip the pin hole in the process. I was able to somewhat fix it by drilling a deeper hole, pretty wonky overall...
I decided to email Cardiosport to ask them if I could buy an empty case. They responded quickly; offering to sent me a replacement case, totally free of charge.
Now, that's customer service. I can think of quite a few US-based companies that should take notice.
