<HTML>Hi,  Although I'm a piano technician,which is my main income,I own a music store,and am a Young Chang dealer.If the customer has a defective product,it has to be fixed, or replaced to their satisfaction (in my store).But on the other hand ,you can't test ride instruments,just like you can't buy a new car,and take it back after a week,unless prior arrangements have been made,which we do with churches and schools,commonly.The new Pramberger  Platium pianos,are wonderful instruments,for the money,and should be pleasing to them.We go out of our way for customer satisfaction,but some kind of buyer responsibility should come into play. Good luck, Hazen Bannister P.S. ( If I can help ,email me.)</HTML>
