I’m not qualified to write a review, I’m an absolute beginner, but the practise flute arrived today, I can make sort-of-in-tune sounds with it, and feel the (cylindrical) aluminium tube vibrate under my fingers when I play. Cool.
Next year I’ll tell you if, and how, it helped me learning to play the flute, but now I’m just happy to have something with a flute embouchure to toot on 
…returning you to your scheduled evening conversation now…
