Questions about returns

Do I need a label?

Yes. In the returns portal you enter your order number and postcode and get a label to print straight away. Stick it on the parcel and drop it at a service point of the carrier on the label.

How long does a refund take?

We approve the refund as soon as your parcel is in. Your bank or payment provider then takes 2 to 5 working days.

Can I return a Mystery Gift or program?

Digital products are delivered by email straight away and cannot be returned. Your KneeMax sleeves can.
