I can testify to this statement...I bought the "valivinators"....they work...also, you don't have to replace them when you flat...nor does the inside one come off when you replace rim tape...
I had forgotten but was reminded when I opened up the tires to put on the electrical tape (waiting for the valvinators) that I had used spoke hole plugs instead of rim tape on these wheels. The lack of rim tape at the valve hole was likely an additional cause of the noise.
