I bought this from E-bay as a replacement for another one we have owned since 2001. It lasted almost exactly three years. First the sound started fading out gradually, and then just completely died. We took apart to look at it - it's obviously an electrical failure in several places. Too late to return under Amazon's policy, so we'll start looking into sending this thing back.
Bad review
