Although the most suitable badminton can be finalized after trial, you can still have a rough judgment on the quality of the ball through some differences in appearance among the many choices recommended by the clerk.

The ball in the badminton store is generally a "professional" ball, that is, a white-headed ball, using duck feathers or goose feathers.
First, look at the ball. The shape of the ball head should be round, the wood should be soft, and the sheep skin film should be thin and firm. When you choose whether the ball support is good, you can pinch it with your hand, or you can gently lift the ball up on the racket a few times.
Second, look at the feathers. The first thing to look at is whether the feathers are tied, whether the round shape of the ball is round, and if it is deformed, it is not a good ball. Feathers are as white as possible (except for special dyeing). Feathers should be uniform in length and length, evenly spaced, and the hairs should be the same thickness. There should be no problems such as hair loss, broken stems, and insects.
Third, look at the quality of work. The quality of the work mainly depends on whether the glue of the ball is evenly applied, whether the knitting of the coil is uniform or the like. The uniformity of these details will have an impact on the resistance of the ball.
Fourth, look at the average quality. Compare the different balls in a ball to see if the quality and appearance are consistent or very close. If there is a significant difference, the quality control is poor, and it is difficult to ensure stability.
