The quick-collapse ball hopper folds up and holds 100 balls. So despite its incredibly compact and lightweight frame, you won't sacrifice ball capacity.
And the Proton's innovative LED indicator means you'll never be guessing when to split step again. An easily visible light, even in bright sunlight, alerts you when the next ball is coming and it's time to prepare.
So start playing better tennis sooner. Imagine being able to work slowly and methodically whenever you want - and then being able to practice against any shot, speed, and spin - all with the same machine!
