Keep portability connected to actual use
100-ball hopper; rolling bag sold separately.
Proton deserves attention when carrying the launcher is the obstacle that prevents practice. Think beyond the machine's headline weight to the complete load, including balls, racket and anything needed for transport. A smaller hopper may be entirely workable if your sessions use short, purposeful sets. Its tap-to-aim approach is most valuable when it helps you recreate a planned feed quickly, so try that editing task before judging the app by its feature list. If your sessions involve several players and long uninterrupted baskets, weigh those needs against the attraction of a lighter carry.
