Kshavi Tennis Trainer Rebound Ball,Solo Training Equipment Self-Pracitce,Portable Tool Tennis Kit

The base of the tennis training tool is filled with water or sand and becomes heavier instantly. This design allows it to be perfectly fixed in place without shaking; the anti-skid pad at the bottom of the backboard increases the friction with the ground and improves the stability. A special device for connecting anti-wrap hooks is added to the outside of the ball seat. When used with the anti-entanglement hook, the rubber band will no longer be tangled.
