This flute is essentially filling the same purpose as a Yamaha 272 -- except that's it's less than half the price of the Yamaha.
Compared to the Yamaha 272, the Thomann is quite significantly harder to handle on the low notes, and generally less tolerant of bad embouchure (I'm thinking of the D in particular which starts very slowly if you try and just lazily breathe on it). It's also, for me, a little bit breathier and more difficult on the high notes. It also seems slightly heavier. Then again, in terms of actual sound, most people don't seem to be able to tell it apart from my 272.
BUT, it's less than half the price. For 200 pounds or so, it's a great alternative -- a beginner might well be better off spending 200 pounds on this and not having to worry too much about how they treat it, and then going for a step-up flute later.
So, I like this flute. But you are getting what you pay for -- it's not as good as a 272 and it's not as forgiving.
