I'm a music teacher and am pretty particular with how music instruments sound. I want the instruments to be of good quality no matter how young my students are who will play on them. I was looking for a glockenspiel with sharps and flats that sounded great but wouldn't take up so much space for storage in my music studio. I took a chance on ordering this one and I'm super happy with it. The overall tone quality is good and the bars have a nice weight and thickness to them. They vibrate well, yet are attached very sturdily so as not to fall off when folding
