Nuvo Soprano Recorder black

Because of its 'innovative' concept, I bought this Nuvo soprano merely out of curiosity.
The build quality of this soprano is OK (be it not more than that), but I found the sound quality very disappointing.
The lower octave is quite good, but the upper octave is mediocre.
Moreover, in the upper octave the recorder is not really forgiving when half-closing the thumbhole.
In spite of its low price, in my opinion both shortcomings make this recorder useless as a school-recorder.
Since many years I am a happy player of plastic Yamaha sopranos (YRS-24B and YRS-302B) and I can recommend these instruments to everybody who is looking for an excellent low-budget soprano.
