The Playmate Grand Slam Ball Machine
I am stunned at how dramatically commercial grade ball machines have improved since my playing days of yore. In fact, my personal ball machines that I have been writing about over the past few weeks are generally on par with the commercial machines that I grew up with. More recently, I am enjoying almost unlimited access to a modern commercial grade Playmate Grand Slam ball machine. It is a lot more powerful than the battery powered personal devices that I own.
