Query: Cushion Massager

My wife uses this in the passenger seat on long trips in the car to ease back discomfort.It works well for what it is designed to do. The only drawback on this and other similarproducts is that the massager must be turned off every 15 - 20 minutes to avoid themotor burning out. This somewhat defeats the purpose on a long ride, but is still satisfactoryoverall.
