    Not a satisfactory return policy!
  

*by I***R on Reviewed in the United States on December 25, 2023*

My lutherie suggested that using this item may cause mold in my instrument.I do not like the return policy from this company and will never do business with them as a result!

this came apart into my cello right before a concert. This product is garbage.

### ⭐ 1.0 out of 5 stars







  
  
    Broke 1st time out of the bag
  

*by M***6 on Reviewed in the United States on December 4, 2021*

Bought this for my son's cello as he has one for his violin and his cello teacher recommended he get one for his cello. Bought this and 1st time using, the black part broke off and now the green part is stuck inside his cello. Can't even return it, because it is stuck inside the cello. Absolutely useless product. Do not buy. I can't even get a refund from Amazon as they want me to return it. I can't return it. It's stuck inside the cello!
