Quite interesting instrument given its selling price. By far the best of all you catalogue of products I have tried and the only one I would recommend to a beginner to learn to play quite seriously before purchasing a real instrument. I am happy to own one and I play and discover new interesting nuances of sound within a plastic tubing and embouchure. Nonetheless, keys are still a bit noisy (which I am sure it is a hard problem to solve) particularly the low C and C# mounted in the foot and B and B flat being the flute operated by the left hand thumb. I also think you should work out a more advanced plastic head joint with a better lip plate and embouchure (even if it comes at slightly more expensive price) that allows better sound dynamics and a easier higher pitch notes quite hard to get from high G and beyond. I was also wondering why not to increase the quality of the plastic tubing used in this flute and use material of the same quality as the ‘ Toot’ model. A better work could be done adjusting the keys and plates and limiting lateral displacement and spacing, which is responsible for key noises and imprecise playing (keys moves laterally 2-3 mm since I received it). Overall interesting instrument for beginners to learn and for advanced flute players to explore new sound nuance, closer to wood (by the way, for when key less copies of baroque or traverso flutes ? There is a niche to fill for lower cost plastic instruments) than to Bohem system metal flutes. The flute case is sturdy, made of rough plastic which but does not look very nice and it is too bulky for what it is. It could be better designed to integrated space for the kids lip plate and tool. In sum, worth developing and improving it as a low cost, sturdy instrument that might make beginners and even advanced players as myself progress and develop new skills and nuances.
