The rubber pump series is very simple to use. The thin tube allows the player to easily put it into the channel, squeeze the pump into the air (one time), and make the expanded end squeeze the inside of the channel. Feel a certain amount of pressure to train the back of the court. Enjoy the fun of the backyard anytime, anywhere. ※ Prohibited! Secondary squeeze pump! Excessive pressure may cause the membrane to rupture.
