Made my carpal tunnel worse

My carpal tunnel syndrome didn't happen for ten years before I started using it. This product may appeal to many, but carpal tunnel makes it dangerous for those with previous carpal tunnel problems. This provides a really good workout and helps focus your eyes, but when the racquet hits the ball the resistance/impact is 5 times greater than tennis courts. So it's like hitting a 5 pound tennis ball with your racquet. So 5 minutes of exercise creates a significant strain on the wrist. I'm so disappointed because the concept is good but now I have to take a few months off from tennis to recover from my wrist injury.

Pros
  • Slim design
Cons
  • Interchangeable
