Delivery is fast, product is what stated on description. I did recommend this website to a few of my friends and they made purchases too. Although it's weird, me myself and my friends are Malaysians and we are buying racket from Malaysia being delivered to US. All in all, great service and great website."

I am very happy with the rackets I have bought from you, they are top quality and hold up when I string them at high tensions. Great discount, and flexible to what I want.
