We completely understand your excitement to receive your order! If your order is taking longer than expected, there’s no need to worry or take any action.

We process all orders as quickly as possible, and any delay usually means something unexpected has come up.

Still, if you have any concerns or questions, feel free to contact us — we’re happy to help.

Also, please check the announcement bar at the top of our website, where we post updates about any general delays.

The most common reason for this is that the package was handed to someone nearby, such as a neighbor or building manager.

We recommend first checking with those around you.

If the package is still missing, please contact the shipping carrier’s customer support directly through the tracking number website.

They can provide detailed delivery information, including who the package was delivered to and where exactly it was left.

Yes.

Unless you selected a DDP (Delivered Duty Paid) shipping option at checkout, our prices do not include taxes or duties, so you may need to pay them upon receiving your order, depending on your country's regulations. If you did choose DDP shipping, taxes and duties are already included in the price you paid.

I want to order from a country with strict importing rules. What should I know?

We have been informed by customers living in countries with strict importing rules — such as some Muslim countries — that there are generally no issues with Customs as long as the order does not contain prohibited content.

Our products are labeled as “fitness devices”, the packaging is plain and unbranded (containing no forbidden material).

However, even with these precautions, it is still possible that your order could be held or rejected by Customs as a “forbidden item” depending on your country’s regulations.

We are not responsible and accept no liability if your order is rejected by Customs in any country with strict import rules.

If this happens:

If the order is sent back to us:

• You may request to have it shipped to another address in a different country (additional shipping costs must be paid).
• You may request a refund, subject to our Refund Policy.

If the order is not sent back to us: 

• Unfortunately, we cannot offer a refund and are not liable for the loss.

Ultimately, it is the customer’s responsibility to be informed about their country’s import policies regarding restricted items before placing an order.

If you are unsure, you may consider ordering through a package forwarding service located in a country with more flexible importing rules.

No, we're not able to do this. We declare the true invoice value on all customs paperwork, and we're not able to under-declare it, even by request.

Please don't ask us to falsify the declared value, customs duties are determined by your country's regulations, and it's not something we can work around. We appreciate your understanding.

We test every single clamp before shipping, so you only ever receive a working one. The most important thing to know when using your clamp for the first time is how to properly connect the tubing to the air valve, if it isn't seated correctly, the clamp won't inflate. Please watch the quick start video guide to see how it's done.

The most important thing to know is that the tubing needs to be wet in order to slide all the way down until it reaches the bottom of the valve. You can use water or oil to wet the tubing. If the tubing is not pushed all the way down, the seal won't form and air will leak.

There are four possible scenarios that could be causing the issue. Please follow the steps in order and only go to the next one if the current one didn’t solve the issue:

1st Scenario – Hose Not Properly Inserted

• Problem: The clamp doesn’t inflate at all and leaks instantly.
  
  
• Solution: To verify this is the issue, inflate the clamp and immediately close the air valve. If there is no air leak, this is very likely the issue and you only need to properly install the tubing against the fitting.
  
  Firmly push the hose while twisting it into the fitting. Please watch the quick start video guide to see how it's done.
  
  The most important thing to know is that the tubing needs to be wet in order to slide all the way down until it reaches the bottom of the valve. You can use water or oil to wet the tubing. If the tubing is not pushed all the way down, the seal won't form and air will leak.
  
  If you are still struggling we recommend you put some vaseline or similar around the tubing so the seal is more strong.
  
  

2nd Scenario – Clamp Not Tight Enough

• Problem: Air is still leaking, even after closing the air valve, which indicates that the clamp is not tight enough.
  
  
• Solution: Carefully tighten the screws as much as possible without overtightening (to avoid damaging the clamp). Then, inflate the clamp again and check for any improvements. To make sure the screws are properly tightened, turn each one until its tip sits flush with the frame at the exit hole.
  
  ⚠️IMPORTANT: Frames must be as parallel as possible; misalignment will compromise their integrity and may cause cracking. The easiest way to ensure this is by checking the screws on the bottom frame — when all screws are at the same depth, the frames are properly aligned.
  
  

3rd Scenario – Damaged Silicone Sleeve

• Problem: A leak may be caused by a tear, puncture, or other damage to the silicone sleeve inside the clamp.
  
  
• Solution: Visually inspect the sleeve for any signs of wear or damage. If the sleeve is compromised, it may need to be replaced. Contact us so we can arrange your replacement.
  
  

4th Scenario – Air Valve or Pressure Gauge Thread Leak

• Problem: If a significant leak persists (minor leaks may be acceptable if the clamp remains functional), the issue may be coming from the threaded hole where the air valve or the pressure gauge is installed, or both.
  
  
• Solution: Apply glue from the inside of the tube around the threaded holes where the air valve and/or pressure gauge are connected. Super glue is recommended, but any glue that can create a strong, airtight seal will work. Be careful not to block the airflow. Allow the glue to fully cure before testing the clamp again.
  
  ⚠️IMPORTANT: Do not unscrew the pressure gauge or air valve from the inner tube. Doing so will only make the damage worse and can cause irreversible harm.

If you are still experiencing issues after following all of the previous steps, please contact us

To make insertion easier, push as much air out of the sleeve as you can with your hands, and at the same time close the air valve (without the bulb attached) so the sleeve stays deflated. This makes the opening wider and easier to insert.

When pulling out, you can leave the air valve open (without the bulb attached) so the air pushes itself out as you pull.

You can also use a vacuum pump to draw the air out of the sleeve. The tubing is 8mm outer diameter and 4mm inner diameter, in case you need an extra one for the pump.

Before troubleshooting the seal, first test the vacuum cylinder on its own to make sure it's working properly.

If the issue persists, start by cleaning both the silicone gasket and the vacuum cylinder so no debris is interfering with the seal. Then check the setup: make sure the cylinder is properly centered, and that the silicone gasket is correctly seated and not stretched when you place the adapter on top.

Before applying vacuum to the cylinder, inflate the clamp just enough to form a seal around the base of the shaft. If you skip this step, the vacuum will leak through the base.

A few things can further improve the seal: applying a small amount of Vaseline, adding a silicone sleeve or toe shields to the cylinder's base for extra sealing, and trimming or shaving hair around the base so the clamp can sit flush against the skin.

Once the whole setup is ready, you can test it on a flat area of skin, such as your forearm or leg, to confirm the vacuum is working. You'll see the skin being drawn up into the cylinder if the seal is holding.
