Master Sports made the Prince Tennis Ball Machine until 2006 when it changed the name to SAM. Expect the same high quality ball machine offered by Prince.

The Prince ball machine was manufactured for over ten years by Master Sports under a license agreement. Master Sports is a premium quality sporting goods equipment manufacturer and distributor. In January 2006 Master Sports changed the Prince tennis ball machine name to SAM, which stands for “Sports Action Machines.”

What is the difference between the Prince ball machine and the SAM ball machine?

None. The machines are exactly the same in terms of features, only the brand name is different. The SAM ball machine is manufactured on the exact same production line as the Prince ball machine and is subject to the same rigorous standards as the Prince ball machine. Here is a chart showing the Prince Brand models and their corresponding new SAM Brand models. Again, only the name has changed, all features remain the same.
