Query: Defective Item!

Poorly made product. Arrived with pieces fallen off and missing. Took it to local music shop and after putting it together there were air leaks around valves so he could not play the scale right. The investment to make it right was around $70 and he predicted we would need frequent repairs. Now I'm fighting with the company for a refund. Avoid this product. My experience was bad.
