I too have never heard of them. I went to their website and pretty much read it all word for word. Definitely got my attention. Especially when the site noted how it was built for smaller handed players. I have a small hand and have been frustrated trying to make some of the long reaching chords especially the ones that use the pinky finger. Barre chords are pretty much a no go. I would definitely be interested in trying one out or hearing from others who actually have one.
This trying to get my left hand and right hand to work together is driving me crazy!
