I previously had a similar Yamaha recorder (German), and it worked well. I know some professional musicians who use these recorders and say they are perfect. I also heard opinions that these recorders are not "true" because they are plastic and cheap.
Come on, they are plastic and cheap, they are tuned well, very easy to use! Maybe they are not "true", but as long as they sound great, I don't care.
I think it's a great modern instrument, and it also looks nice.
