I use it for several months.

Obviously the most is the price (just over 150). He also does the book in a box trsrsistante transport.

Are the least
* Weight: heavy for a paperclip more "standard": do not buy for a child as too heavy,
* Accuracy (we lost almost a half-tone on one octave), but a beginner will not notice too much beginner in any case - be careful not to adjust cons by the note of forming a mask / breath - as a beginner is better to leave a note + / - false in accordance with the instrument
* Finishing & Co, Made in China ", standards Franaise / the European are not necessarly taken into account, especially as regards the patent (cancrigne? - Note that old Brass instruments need to be equally, however ...).

So one has for his money (not much), this trombone is a musical instrument and not a toy unplayable.

If I keep practicing this instrument a few months I m'achterai a model that has a little more recognized by music teachers to be a good study of trombone (=> less cumbersome and more accurate ).
A priori, so it takes about 400 for such an instrument.
