I buy my Saitek Eclipse II May 2008 and two of the key start act up late August , the n key give 7n while b key give 4b . I call up they technical support and ask about the warranty service . the guy be nice , he request the proof of purchase . I give he the invoice from amazon.com . it have be over two week , the last thing I know be the request for replacement keyboard have not yet be approve . I think you need to know about both side of this product : it be good keyboard when it work . the quality be not as good as I expect . do not throw away the old keyboard as the warranty service could be a lengthy one , if it work at all .
