No practice partner? No open tennis court? No problem! Practice your forehand, backhand, serve and overhead smash by yourself with the Fill N Drill™ Tennis Trainer from Unique. Use it in a tennis court, driveway or garage.
- When filled with water, the Fill N Drill™ weighs 43½ ounces. That's heavier than if it was filled with concrete.
- When empty, the trainer weighs a modest 7½ ounces making travel a breeze.
- Strong rubber cord returns the ball every time.
- Non skid base keeps the trainer in place.
- Can be used on clay courts by driving a spike (not included) into the court and positioning the handle over the spike.
