Comments about Spalding NBA Official Zi/O Excel Indoor/Outdoor Composite Basketball (29.5):
I use this product for indoor and outdoor games. The size is good, the fact that it's for indoor AND outdoor games is even better and there's no reason to upgrade to an official ball if you already have this.
Bottom Line Yes, I would recommend this to a friend
