【2020 New Upgrade Design】: Fill the base with water or sand and it instantly becomes heavy enough to hold the unit in place. The non-skid pads at the bottom of the tennis trainer rebounder increases the friction with the ground and improves stability. A special device for connecting anti-wrapping hooks is added to the outside of the ball seat. When used with anti-wrapping hooks, the rubber band will no longer be entangled.
【High Quality Tennis Rebounder】: Our tennis ball rebounder is made of sturdy, durable and quality high-density PE plastic, with 2 high elasticity and wear-resistant rubber ropes, 2 tennis balls, 1 metal clip and 1 baseboard. And the upgraded elastic rope is very high resilience to bear intense tennis training. Free to practice all kinds of strikes including full strikes.
