Tennis is a fun sport to pickup but takes a lot of practice to master. With a decent tennis ball machine, you can program drills to work on your weaknesses. The Spinshot Plus-2 can help. It has room for up to 120 balls and lets you use your smartphone to program speed, spin, height, angle, and other settings.
This machine also has a control panel that lets users easily choose from preset drills. A watch remote is also available. The Spinshot Plus-2 can be powered by a battery or upgraded to a power & battery module for AC use.
