Now you can have a reliable partner -- one who is never late for practice, always returns the ball consistently and whose game improves with yours. The REAListic Tennis Backboard's unique double concave design (top to bottom and side to side) focuses balls back towards the center of the court, increasing the number of hits per rally and therefore increasing the value of the time spent practicing. Weather impervious hitting panels are guaranteed for ten years of daily outdoor use. REAListic Tennis Backboards are available in three sizes (8' x 8', 8' x 12' and 8' x 16'). Available options include sound reduction kits and ball containment netting systems.
