Jsbeuith Tennis Trainer Rebound Balls - Tennis Trainer Equipment Trainer Base - Self-Study Practice Training Tool Training Gear for Kids Player Beginn

My Advantages: -----I works really well on the driveway. -----Filled with water, my base stays in place really well, if not enough, you can fill me with sand instead of water .Even better if you fill my base with play-sand and water together, you can hit the ball hard, I will stay securely in place . Also you can put a rock on me to increase stability. ------- I may not last forever but I am less expensive than one lesson or an hour court fee and I can make you play alone when your partners are not be able. -------I work very well as I allow you to practice your forearm and backhand, include footwork. You can then rally the ball switching from forehand to backhand, while establishing proper footwork with me. As a result,I will improve your reaction timing. -------The big plus is that you can take me with you anywhere, and use it anywhere there is some space and a solid floor for the ball to bounce. My shortcomings: ------The ball is easy to fall off the rope------The next batch of goods will add additional elastic cords to each package, you can connect 2 or 3 elastic cords to the ball. So you can do your best without breaking the string, and the tennis ball will rebound quickly. -----If you think Bounce back is low and inconsistent. ----------You'd better Better to find a wall. I can work better with that. ------- It was a bit annoying to fill up with water (it would help if the filling hole was a bit larger)-----------I are trying to communicate with the factory whether they can widen the water injection port. ------The hitting of the ball requires you to take some time to get used to. you can't just hit the ball anyhow otherwise the ball will come back from all sorts of angles. --------The tennis balls that come with me may be worn out very quickly ----------- temporarily you can only get replacements for a few dollar a piece. I will add an extra ball for the next shipment to facilitate your replacement.
