The Wilson Portable Tennis Ball Machine $680 Call:

　　Trajectory Control: Adjustable from ground stroke to lob so you can practice all the shots, together with overheads.

　　Spin Control: Adjustable for flat shots, as well as for varying degrees of topspin or backspin.

　　Built-in Oscillator: Delivers balls either in one placement, or randomly across the court which means that you can practice hitting on the run.
