I was actually surprised when this was delivered - I never expected it to feel so well-built and look so good! The paint job is very nice, and the wood seems to be of decent quality. It smelled a bit funny though, so I let it air for a while before playing.
Once I managed to find the technique for producing proper sounds it actually sounded very good! Not a very deep bass, and not the loudest sound, but still good. As good as can be expected from a short woodwind overtone instrument in the budget category at least!
I am no expert on these (to me) exotic instruments, but I have tried a few different ones - including one built from an exhaust pipe and a soda bottle - and this one is among my favourites. Should be good for kids as well (not too small kids, but school children I guess) considering its relatively small form factor.
