OrientalMusicSanctuary ATTESTED: Dong Xue Hua Pofessional BASS Dizi Model 8881 - MELLOW BASS Chinese Bamboo Flute (Right Handed Key of G (Bass))

The first picture shows the dizi with the name "Dong Xue Hua" which I bought. The other pictures let you see what inside the dizi. The BASS G dizi: The inner end of bamboo that connected to the horn is unbelievable rough. There are bumps on the inner surface which can infect the timbre. Even a 2-dollar dizi I have is smooth inside. The bB dizi: The horn of the end is cracked. It doesn't have to be horn. It can be plastic or resin or anything, but no crack plz. The only rating I can give is-Shoddy and poor quality product. As the seller marked, the dizi was made by Dong Xue Hua, a famous dizi maker. And the seller told me "Dong just made it for you" in the phone call though it made me felt strange. But in fact I don't care who made it, what I expected was it worth it's price. I had the last picture that shows the smooth inner end of another dizi I bought with 16 dollars. Do you guys think these dizies worth 90 & 75 dollars before tax? I can keep the dizies, but I ask for 80% refund.
