I am not certain, but I believe I saw this product (or one similar) on a popular TV show here in America a few years back. I thought it was a great idea then, and I think it is a great idea now. If I remember correctly, one of the investors on that show thought the same! Now the cord buddy at guitarcenter.com can be purchased online or at a location near you. If you want to learn chords, and how to play the guitar in general, I recommend it.
