I think the target market may be kids, but there are many who use these kind for travel. So, from this perspective, these are my notes:
Pros: Cheap. Small, the body fits in a backpack with the neck sticking out which I bag. I also use a 1/4 gigbag. Very good sound actually. I like the sound of top 3 nylons; tone is clear and easy to sing with (baritone). Surprisingly loud for its size.
Cons: Requires tinkering to get most out of it, see below.
Easy: I tuned this one 5 semitones up so it's exactly the same as standard with capo on 5, including fret lengths; ADGCEA. The strings become too loose for standard EADGBE.
Moderate/hard: The strings are too close together, and they don't sit in notches near the hole (!). I widened the strings and sawed small notches in the white part near the sound hole. Guitar stays in tune and strings are as wide as on a normal electric guitar.
If you want to attach a strap, you'd have to remove strings and drill a hole and attach at least the bottom nut. Though, the guitar is so light the strap may not be necessary.
