Herman, if you've got the brains to produce this stuff - why hijack other peoples inventions - why not make something totally original? A few years back nobody produced a really good swivel for wfp - unfortunately for you it's been done now - very well too.
Maybe ask around and find out what people really need then get your thinking cap on? Not being funny, but I don't think I've seen a single invention of yours that's not already selling in some form or another.

In the video this is only to show how it works.

All know that this is different in every way to any squeegee handle on the market including the rotation mechanize.
You always saying that it is out there how about showing everyone what you are talking about.
Then we will all know what you mean.
