What People Are Saying...
I have purchased 4 rackets and various bits of clothing. I have been very impressed with the quality of all products.
I have also got all goods purchased within a week of ordering. (fantastic).

A very satisfied customer"



Lloyd A. , Australia

Your service was great.  The racket is really good too.  The only thing was that the box arrived with some signs of crushing, and a few tears.  I am thankful to God that the racket inside was still in good shape.

Thank you very much.  I will definitely buy from you again, and recommend you to my badminton playing friends."



Jim , United States

Yes I am very happy about good purchased from Badminton Bay. I just find difficult to choose racket because descriptions are too similar between them. If you can improve raquets descriptions, I think it will be more helpfull for customers.
Thank you and see you soon."
