I haven't given it yet. So I can't really rate it. I'm sure it'll be wonderful!
The little details are hard on fingers, but it is worth it. Not only does it look great, but it's also quite fun to play. You can tun the drone tone to be the same as the melody string or lower it down a third and receive half a minor scale! It has a limited amount of notes and the higher the notes get the more out of tune it is, but its really, really, really, really fun! And it's not like Lego that you build once and thats it, thats the fun. This fun keeps going. I love it!
It is pretty good, but it would be better if it would be a major line instead of how it is now. So for example for C it should be:
and not how it is now:
One could play far more Songs with this.
But it is still good!
