Query: Not as good as I thought it would be

I tried this product and discovered that it didn't quite work as advertized or nearly as well as I had hoped. It sure did seem like a reasonable idea when I saw it, but it just didn't get the job done! I ultimately had to created my own method of blade balancing that fortunately did work! Sorry for the less then stellar review, but that was my own personal experience.
