The bars work as expected (penetrating pleasant tone that reverberates long). Perfectly suited especially for educational use, as it looks, musically speaking, I sadly can not say. A star deduction there was due to the lack of care in the processing of the product (where the wooden board for mounting of the bars was cut, the wood splintered off easily and the chimes have a few scratches) All in all, a good product, since it depends not necessarily on the optics.
