I test the xylophone ASARET APX35-3, 3 and a half octaves in its flight case. We can say that it is a good product given the excellent quality price ratio. If it is to use the house everything is OK, but if you must group play with other instruments such marimba or vibraphone, you have a problem of incompatibility because of the harmonic Asaret are granted the fifth when nearly total other instruments are the major third, attention to the ears!
