Tennis Rebounder is great for tennis training or other racket sports. This is a new XK Sports Tennis Rebounder (still in the box) that is comparable at $472 online. We used the same model for a few years before lending it to someone. They liked it so much they kept it and sent us a new one as replacement. Great for practicing your strokes and getting into a good, consistent rhythm. The rebounder can handle full force swings and returns the ball back gently and consistently for the next shot. Works well for kids or adults.
