Well, my harmonies had a defective needle (wouldn't tighten on the cord just kept turning and turning) and it's already been replaced! They insisted on replacing the defective cord I have as well, without it being returned, but I had already sent it back so I don't know what size it was.
I worked in customer service for 15 years or so (till we started a family, I've been an at home Mom for 13 years now) so when I come across people that know how important it is I really, really appreciate it. Especially in a world that seems to have forgotten what good customer service really is. Think I'm going to send them a very appreciative e-mail.
