The Wilson 75 Ball Hopper is not just a stand, but a back saver as well. First, load your tennis balls into the hopper and prop up the lockable legs and hit away. When the basket is empty, simply fold the legs over into handles and place the hopper directly over your tennis balls and they magically pop into the cart through the bars on the bottom of the basket. No more bending over to retrieve the balls, and you can almost guarantee youll have time for more and more reps during your time on the court.
