This machine helps you improve your shots by practicing them over and over again. You don’t get this liberty when you are playing with a teammate or other players. They are sure to get frustrated and bored after a certain point. But a tennis ball machine will let you play for as long as you want until you get perfect with your shots.

This machine also puts up quite a challenge to the player by feeding difficult balls. It can also be programmed to throw different shots one after the other. So now you can play as many shots as you want and keep learning from your mistakes and improve your strokes over time.

So if you want to invest in a ball machine there are certain factors that you need to consider before buying them:

• Oscillation: This is an important parameter to consider before buying a tennis ball machine. Make sure that the ball swings well and covers the entire court by giving variations in shots. You should be able to practice all types of shots such as forehand, backhand, lob and various other shots with the help of the machine. Also check the highest speed of the ball so that you can practice your shots with accuracy. Elevation, speed, height and direction of the ball should be some of the factors that you need to consider before buying a ball machine.

• Portability: This is another essential factor to consider while buying a ball machine. Most basic machines are made of plastic and are not more than 5 kg. But the advanced ones are quite heavy. But you can check if they have wheels and handles that make it easy to transport them from one place to another without any difficulty.

• Warranty period: Make sure the ball machine has a valid warranty period. Most machines come with a warranty period of 2 years. Anything below that should be reconsidered as you are buying them not leasing them.

• Battery life: A tennis ball machine can work on electricity or built in rechargeable battery. But the electricity-run machines are not quite convenient if you want them to be portable and play in a place where there is no source of electricity to plug in the machine; for example outdoor parks. Rechargeable batteries are much more convenient as you can charge them and carry them to different places. Usually a single overnight charge will let the machine operate for five hours.
