Prop Balance Master

I ran across this looking at plane parts and had never heard of them before. I'm curious if anyone has ever used this and if it works to help balance props?
I fly a Piper Archer now but have a Kitfox on order. Thanks for any info.

That is something I have never seen before. If it works that would be a great device because you just have to bolt it on. One nice feature seems to be that it does it at all RPMs.

Here is a video showing it on being tested on a Rotax 912:

It would be interesting to test one on a prop that has already been dynamically balanced. I would check the vibration at several RPMs before and after installation.

I have actually saw those work on big trucks before now that you show those .
