Title: Does what it should.
Review: I have used this many times to find out how to forma chord. I am pretty new to guitar so this is a big help. It could, and should, be brighter, but that is my only gripe. It has helped me numerous times already and save me from shuffling through chord books. I have also used the metronome when mine was not available. All in all, if it covers the things you are looking for, it does work and, at least for me, was well worth it.
