To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
You could literally teach yourself to play guitar with this two sided card. It even teaches how to read tablatures with 3 little diagrams. Has all the common first position chords, but I needed sharps, and fifths, and sevenths, and minors and barres and this laminated card has got it all. I wish someone made this card about 2 feet square instead of 8x11 inches. Get one.
