SIMON makes pickleball throwing machines, sold under the SIMON X and related model names. The machines are built from stainless steel and aluminum, throw at speeds from 5 to 70 mph with topspin, underspin, or flat delivery, hold 120 balls with optional hopper expansion, and run 10 to 12 hours per battery charge with an AC option. Oscillation happens inside the housing. The company sells directly through its own online store and includes a lifetime warranty on the two throwing wheels. Machines ship nationwide and are used by individual players, coaches, and clubs.
