Pressurebox is essentially a more advanced, reusable version of the containers in which new balls are purchased. It preserves and
restores the internal pressure of tennis and padel balls by storing them under pressure. The pressure within the container increases the pressure inside the balls. In essence, it operates in the opposite manner to what occurs when the balls are exposed to 'normal' pressure.

Pressurebox is easy to use. Here is how:

1. Remove the bottom lid and insert your balls after play.

2. Close the lid firmly to ensure that it is sealed airtight. However, since individual strenght varies, make sure not to close the box harder, than what will make you able to open it again.

3. Press the main switch and leave it in the on-mode until the next time you play. Pressurebox will automatically build up and maintain the correct pressure.

4. Before opening Pressurebox again, shut off the main switch, press the deflate button on the lid.
5. Open the lid, take out your pressurized balls, and enjoy!

1. No manual pumping is required for the container each time.
   
2. More importantly, the automatic sensor ensures consistent pressure in the container and allows the Pressurebox to add more air when the box's air pressure decreases, maintaining constant pressure. Why is this important? First, all pressure containers experience some leakage. Second, when placing used balls inside, they naturally reduce the air pressure within the container through diffusion. Due to both factors, new air must be pumped in to ensure that the container's air pressure always remains higher than that inside the balls. Without this, which is often the case with less advanced products, it simply doesn't work as effectively.

While the longevity of tennis & padel ball pressure depends on various factors such as playing style and ball quality, it's useful to provide a comparison. Without a Pressurebox, approximately 20% of the ball's pressure is typically lost after just an hour of play, with further gradual decreases over time.

In contrast, when using high-quality tennis/padelballs with Pressurebox, the pressure in your balls will be comparable to new balls, even after several sessions & matches.

It's important to note that individual experiences may vary, and the balls may show some wear and tear after prolonged use, such as the logo becoming less visible. However, in most cases, the playing experience remains satisfactory even after extended use. For padel, the impact on ball felt is even less, leading to an even longer playing time.

The short answer is that it depends on the condition of the balls used, since Pressurebox works gradually on the balls.

The most common usage of Pressurebox by regular players with high playing
standards, is to buy new balls as usual, then put them in the box each time after play, which will allow you to play with the balls much longer and increase ball quality, from the second session of play and onwards. In this user case, Pressurebox will usually get the pressure back as soon as the next day, or shortly thereafter.

Note that completely pressureless balls can not be inflated again. For the quickest & best results, it is best to use balls that has a decent amount of pressure left in them - which usually is the case even for many leftover balls that can be found anywear in tennis & padel clubs.

Please try the steps below if you are experiencing one or more of these problems:

- The product is leaking air
- The compressor restarts often
- The battery life is shorter than expected

1. Ensure that you are using the product in on-mode, and that you have closed the lid firmly.
The product is generally more airtight the harder the lid is closed, but don't close it so tightly that it's difficult to open again.

2. Check that the threads of the lid and cylinder are clean and that no dirt is stuck.

3. Take out and adjust the loose rubber O-ring on the inside of the lid, using this quick guide.

4. If none of the above works, use this quick guide to adjust the top part.

If the problem persists, please reach out and let us know how the performance of the product changed for each of the steps 1-4. This information will be required for us to understand the issue.

For any problems related to electronics, try these steps:

1. Leave the device off overnight.

2. Recharge the device until all four lights stop flashing. This will reset the device.

3. Ensure the device is disconnected from the charging cable before attempting to use it.

4. If the device doesn't start, firmly tap the compressor part of the box with your hand immediately after the click and/or after turning on the product. This should help if the pump is stuck for some reason.

5. Try removing the silicone cover and using the device without it. A misplaced cover could potentially block the air inlet. To remove the silicone cover, loosen it around the USB-C port and then take a firm grip and drag it slowly but steadily up without folding it.

6. Contact us with a video illustrating the issue with the product without the silicone cover, including the numbers on the lid & attach your receipt/order confirmation.

Answer: For ease of opening, make sure not to close the box too hard.

If you have closed the lid hard and are having trouble opening it, there are a few tricks that you can try.

1. First, make sure that you have deflated the box. If you still can't open it, try using a glove (skin gloves give the best grip), towel, or ask someone strong to help you.

2. If it still does not work, try to gently knock with a spoon around the lid (this reduces friction), and then try to open.

3. Remove the silicone cover for better grip. Just push it up, and it can be removed. For the next time, check the inside of the lid for dirt and follow the steps for airtightness and close the box softer.

4. If you are still having problems to open the box, let us know, and we will help you out.

Situation: The balls are too hard. 

Solution: Since the pressure inside Pressurebox is higher than the internal pressure in tennis & padel balls, the balls can sometimes get too hard if they are in the box for long. However, this is an easy problem to solve. Just open the box some time before you play, and the balls will get softer, as long as they are not stored under pressure.

Situation: The balls are not hard enough. 

Solution: If the balls used are too soft & old initially, it may take some time to restore the pressure. It is advisable to use balls with some pressure from the start and utilize the Pressurebox frequently in between each session to maintain optimal pressure.
