12 yuan (PVC material)-more suitable for outdoor concrete floor;

14 yuan (PU material)-both indoors and outdoors

18 yuan (PU material)-both indoors and outdoors

The above are the basic common balls, and those over 3 and over 1 (leather) are used by people, with different consumption levels.

I personally bought one from 14 yuan some time ago, and it feels good. If you are an ordinary basketball fan, it is recommended to buy a ball made of PU material from 14 yuan or 18 yuan, which can be used indoors and outdoors (preferably in a plastic factory). Too expensive doesn't mean much.
