Hello, I'm glad to answer your question. Since your boyfriend likes basketball very much, give it to him. This is the most practical, and other small things like wristbands are easy to lose. At the same time, if you can afford it, you can send a ball signed by his favorite star. If not, it is recommended to sell it yourself. Good basketball lies in quality, not brand. Spalding is good, but it's too expensive. In fact, the quality of basketball can be tested and can give you some standard data of basketball, but it is difficult for you to apply it in practice. When choosing basketball, you can use the following steps: at first glance, the surface is flawless. Sometimes the brand-name meatballs bought in the supermarket cost 40 to 50 yuan each, and the surface is often flawed. Although it does not affect the use, it is best for personal use and not suitable for giving away. The second smell: the good material has a fragrant leather smell, and the bad one is rubber smell; Three presses: the good ball can't be pressed even if it is not full of gas, while the bad ball is full of gas, and one press is a pit; Four points: balls that are too light and too heavy are not good, but most people can't figure it out, and everyone who must play often knows it; Five bombs: let the ball fall freely from the top of the head to see if the rebound is straight. On the flat ground, you should fall many times and stop at the same place instead of rolling away. Whether the height is below waist and chest.
