Tianlong is a domestic tennis manufacturer with a long product line. I participated in some competitions in 20 14, and the ball used in the competition was Tianlong pound.
The feeling after use is: moderate elasticity, fast pilling, and the ball speed will decrease after pilling. Relatively speaking, it can be regarded as a game ball in domestic tennis. Tianlong's 603, Rising and Feel have all called. Personally, if you play games, basically these three modes are useless. The air pressure drops quickly, which has a great influence on the ball speed. As a daily training ball, it is still possible. However, compared with the non-pressure ball, the service life is shorter.
