Is this a good brand of flute?

Absolutely horrible TRASH it is. Your ear just seems not to get used to hear any difference between trash and of good quality instruments because flutes cannot be ranked only in terms of how they look like! Besides, good flutes are NEVER coloured purple, red, blue or anything like that. Furthermore, the good brands are always very well-known anyway, Yamaha/Pearl/Jupiter for example, so please do try to get some more information about the brands before wasting your money on anything so bad as this!
