Comments about Trend Sports Heater Pitching Machine Baseballs by the Dozen:
These balls are nice quality. They are solid with a slight squishy feeling. When used in the heater pitching machine they come out slower because of their weight. If they get wet or damp they are even slower through the machine. My not have enough velocity to make it farther than 10 feet when wet. (wet because the grass is damp) When dry they can go far enough to simulate a pitcher. Not perfectly but enough for back yard practice.
