"He who marches out of step hears another drum." ~ Ken Kesey
Gerr's problem is along the edges where it is fastened down. I know we went through that problem with our old vastex unit. Once it started to rip around the edges I took it apart rolled the edges to give it a hem and refastened. I also doubled the amount of hold down screws to give it some more life. It tightened the blanket up some but it did last for years.
