I have just purchased Astrox 38S, after few sessions of playing.. Well, I must say this is one of the best low end racket that I have ever use! Do not trust people that say Yonex low end is bad, vibrate really hard when smashing, bla bla. Honestly I don't feel it that way.

Cosmetic and design wise, it is really pleasing. I can stare at this racket all day.
Spec wise: great speed and swing in the air, perfect effortless defense, and decent smash power. Btw I am an intermediate level of player who always play doubles. If you think you need more weight in the head, go with 38D or even 68D for a lot more head weight.

In conclusion, for that range of price, Astrox 38S won't disappoint you. I can guarantee that.
