There is all kinds of wrong with a $15 pre-made ping pong racket from Walmart (a chain retailer in America and some parts of the world). This boy in my club went to Walmart to buy a racket. He had money also to buy a little expensive one, but ended up with this cheap paddle that costs only $15.
At the end of the day, the blade has shown its real behavior. The blade bend like a big spoon. According to the boy, the blade was straight when he has bought from the store. He is on the look out for a good racket now.
I will write a blog later on how to prevent blades from warping.
