After much research I bought this guitar for my daughter who is taking guitar lessons. It is her second guitar, having previously used a cheaper model which, while it served its purpose for a while, did not live up to expectations.
The CS40 II is of excellent quality and it plays very nicely. I believe it holds it's tuning fairly well, though my ear is not good enough to tell for sure.
I don't know what additional features one might expect from an acoustic guitar but it does not lack anything and at an entry level price it is very much a great value.
