Why We Recommend You Use SetPoint Pulp Pressureless Tennis Balls
Regular pressurized balls go flat quickly in a ball machine as they get hit frequently and are also squeezed through the throwing wheels every time they are shot. When they get flat this can result in inconsistent ball throws and jamming of the machine. SetPoint Pulp Pressureless Tennis Balls were designed with the Spinfire Pro 2 in mind and do not have these negative qualities. They are much more economical over the long run as they last a long time. We do not recommend the budget-priced pressureless balls as they are of poor quality that do not last. You have chosen a premium tennis ball machine and it deserves a quality pressureless ball.
