Query: Unhappy with Bongos Hardware - Poor Quality

The hardware associated with tuning the bongo is cheap plastic - not metal. We asked a music teacher to 'tune' our purchase and on his first attempt to tune the bongos - while adjusting the tuning screw - the plastic holder broke. From our perspective - this is NOT a quality instrument that is worth the money we spent on it - when the hardware is simply molded plastic. I don't feel we received our money's worth on this selection. In order to fix our purchase and make it usable - we would have to purchase new metal tuning screw holders from a music store and retrofit them to the bongos.
