Frequently Asked Questions
Q1: How does the tennis ball pressure retainer work?
It works by applying internal pressure to the balls. When you screw the cap to 14 psi, it creates an environment that prevents gas from leaking out of the balls and can even help restore lost pressure over 24 hours.
Q2: What material is the container made of?
The container is made of high-quality fiber reinforced plastic, ensuring it is lightweight yet durable enough to maintain high internal pressure.
Q3: Is it portable for daily training?
Yes, it features a compact size (approx. 3.3 * 7.9 inches) and weighs only 450g, making it very easy to carry in your sports bag.
Q4: How long should I keep the balls in the box?
For best results in restoring pressure, we recommend leaving the balls in the pressurized container for at least 24 hours.
Q5: What is the maximum pressure value?
The recommended pressure value for maintaining and restoring tennis balls is 14 psi, which matches the internal pressure of a brand new ball.
Q6: Can I use this for other types of balls?
This product is specifically designed for tennis balls to restore their bounce and form. It is a dedicated tool for tennis enthusiasts.
