Query: What a downer

Although I read the previous reviews which commented on the cushion's tendency to break down, I too, wanted to believe the best. I had tried the SBM-200 model in a store and loved it but when I heard the 300 version provided spot and width controls I thought that would be the better gift. Of the 7 times that the cushion was used since Christmas (two days), it was a hit. As my mother said, the best Christmas gift. But then the machine all of sudden had a mind of its own and shut down completely. It only allowed for the demo afterwards. When calling Homedics they said that this was highly unusual but based on the responses on this web-site I find that doubtful. Although my parents would like a replacement model, I don't think that would make the most sense, unfortunately. Until Homedics works out the kinks in this model I think we're going to stick with the SBM-200.
