FretboardFix™ System

Great idea but the product is just made of paper. This was very disappointing. For this price I have purchased more durable aids. If you spill anything on this it will be destroyed. I would recommend making these out of plastic in the future. The item was also poorly packaged and damaged during shipping. Since it is just paper bending the envelope will damage the cards. The answer sheet is not laminated either. I still like its usefulness and would encourage improvements.

Its a good product for learning the fret board!
