I still know a little about the beat of this finished product. There is no difference between azazel and the Blue Devils. The only difference is that the handle is blue and red. The blue one is the blue devil, and the red one is azazel. There is no difference between them. Their sponges are too thin and not very elastic, so it's hard to fight. So I suggest you don't buy any azazel or Blue Devils, if it's for fitness. Just spend 60-70 yuan to buy a double happiness 4-planet racket, because at least the rubber of the racket is g888. It can beat some. I don't know this explanation, can you understand it?
