Yet another awesome “smart” product, the outdoor composite leather basketball by ShootersRev, based out of Arizona, gives you audible feedback on your shots to help you improve and nail the perfect backspin. If yo hear the beep, you’re doing it right. If you don’t, you aren’t. There’s no app to pair with because let’s face it, if you have your phone in your pocket while you’re playing, you aren’t serious. You can even take the sensor out to charge and for when you’re getting a real game going instead of practicing. The price has even come down twenty buck to $75, and it’s available now. Ball dies, but the sensor is going strong? You can get a replacement ball without the sensor for $45 or a replacement sensor for $55.
