When it comes to ball machines, you've likely seen the usual big metal box with wheels, levers and practically zero portability. Tenniix is the opposite of the traditional approach to a ball machine, in that it is highly portable , lightweight (22 lbs), and easy to use, even from the other end of the court via the Tenniix smartphone app. The machine is battery-operated, meaning you can use it anywhere, on any tennis courts. The Tenniix ball machine has two main modes: Training Mode and Match Mode. In Training Mode, users can create and select a specific type of shot that they want to practice hitting against, all curated and adjusted through the companion app. Training Mode gives you the option to choose from practicing against any of these shot types: Baseline Ball, Short Ball, Feed Ball, Volley Shot, Kill Shot, Moon Ball, Hand Feed, Top Spin, and Back Spin. Once the type of shot has been selected, the Tenniix app lets users customize any and all of the following with a slider:
 

• Ball Speed - How fast the ball is dispensed from Tenniix.
• Shot Angle - The angle of elevation for launch.
• Ball Spin (0-5,000 RPM's) - Amount of rotations per minute inputted on the ball (topspin).
• Horizontal rotation (side spin) - A slider for adjusting sideways ball movement.
• Feed interval timing (1-10 seconds)

In Match Mode, Tenniix will time the shots it feeds to you as if they were being hit by a real opponent. This is great for simulating actual rallies, instead of just working on the same shot with the same timing repeatedly. Also in Match Mode, users can adjust the same shot qualities listed above. Players can choose between any of the following rally modes:

• Baseline Rally - Series of shots that mimic baseline to baseline exchanges, with shots landing deep in the court and close to the baseline consistently.
• Deep and Short Rally - A series of shots that switches between a baseline ball and shots nearer the service line, prompting you to attack the point.
• Move Rally - A sequence of rally balls that are designed to make you move to the ball, facilitating better footwork and sharper timing.
• Spin Rally - A shot sequence designed to mimic slice battles or heavy topspin exchanges. 

All-in-all, our team of equipment testers was thoroughly impressed by the functionality and ease-of-use of the Tenniix ball machine. Its highly customizable ball outputs are among some of the best we've seen, and the Match Mode is great at simulating the actual timing of a rally. The portability is another standout feature, as it is easily packed up and slung over the shoulder with a carrying strap. For even more options with voice control, check out the Tenniix Voice Armband Module.

Overall: Tenniix's Basic AI Ball Machine is a one-of-a-kind ball machine, driven by real-time AI analytics. It's great for working on specific shots or for simulating a rally, easily moving you around the court if so desired.
