Fill n Drill Tennis Trainer
This portable tennis training aid is suited to all levels of play and is perfect for warming up, practising your strokes or developing a faster swing speed. Once the non-skid base is filled with water you are ready to go. The robust bungy cord which can stretch up to 30′ returns the ball to you time after time. Great fun in the garden, driveway or garage or take with you to the court or park. When not in use it stores neatly into the empty base, making it easy and light to carry in your bag.
