I have used these to improve my game for many, many years. I highly recommend if you have never used one before. The balls will come back to you faster than if you were playing with another human, so in my opinion, you work harder with this and improve your game. I recommend really paying attention to how high you are hitting it to simulate the net, and use this to focus your aim. I am a High School Varsity Tennis Coach and will be making sure each of my team members know this is an option!
