Read my comparison of this flute with the Sonare alto flute.
This flute has a sonorous, smooth velvety tone in the bass and midrange. It is a truly wonderful sounding flute. But as it goes into the top octave the tone deteriorates a bit. It still sounds acceptable, but not as beautiful as in the midrange and bass. This seems to be the main tradeoff of a budget alto flute.
I like this instrument a lot. It has a beautiful tone, smooth quiet solid key action and is easy to play. The only real drawback is typical of all alto flutes with straight headjoints: it is not comfortable. The straight headjoint has to be pulled out about 1/2" to tune A=440, which has my arms pretty far off to the side. A curved headjoint cures this problem but introduces intonation problems. I have long arms (34" sleeve) so it's no big deal.
