When I first received this it did not work. After making a video to show the tech's it was not working, the response took a few days. The response I received was that that they would send me a new gasket. I did not believe that was the problem. After a week or so I did get a new gasket, but not a replacement one, but the other half that was missing in the original order. If they hadd told me that I was missing one side of the gasket I would have realized the issue. The instruction manual pictures and instructions are so poor that I did not realize I was missing the part.
