Advantages of buying a tennis ball machine

The most obvious advantage of buying a tennis ball machine is for improving your tennis technique. Many tennis players, both beginners and experienced experts, use tennis ball machines to practice returning shots with nearly identical paths and spins in order to improve their technique.
A lesser known advantage of a tennis ball machine is that it allows you to practice and place tennis on your own without needing to schedule a partner to play. With a tennis ball machine, you can drive to the local tennis courts and get in a game of tennis at any time, even when none of your tennis friends are free! Let's say that you are able to meet up with friends to play tennis 3 times per week. If you also practice with your tennis ball machine three additional times per week, your tennis practice time doubles! You'll be amazed at how fast your tennis skills improve while practicing with tennis ball machines.
It's definitely true that practicing your game with a tennis ball machine can be less dynamic than playing with your friend. More specifically, it's difficult to play a real traditional tennis game with a tennis ball machine! Many tennis ball machines have the ability to randomly vary their shots so it's not as though you'll need to practice returning the same shot for hours on end.
I think you'll find that for some things, a tennis ball machine is superior to playing with a friend! We've already covered the fact that friends have difficult schedules and it can be impossible to coordinate schedules in order to play tennis. In contrast, your tennis ball machine is always available! Pull it out of the garage, load it in the car, and you're reading to practice tennis with the tennis ball machine! Another advantage is that your tennis ball machine won't complain and has infinite patience, which is very different from virtually every human friend I have! Your tennis ball machine won't complain when you play at your perfect pace, and won't be annoyed if you want to practice the exact same shot 200 times in a row! Try that with even your most patient friend!
Finally, your tennis ball machine makes it easy to keep your practice efficient. Unlike playing with a coach or colleague, your tennis ball machine can be configured to only serve difficult shots or shots in which you'd like some practice. A friend will get annoyed if you ask him to serve a shot down the baseline every time, or if you ask him to try to nick the net every time in order to practice your technique. On the other hand, your tennis ball machine will never complain!
