Refund policy

Last updated: 18 October 2026.

Free returns and 30-day commercial guarantee

You may request a return within 30 calendar days of receipt if you have not used the product or if, after using it according to its instructions, it does not deliver the advertised performance. This commercial guarantee is additional and does not replace your statutory rights.

To assess a claim under this guarantee, we may ask for photographs or videos showing the condition of the product and the issue. We will inform you of the outcome and, where a return is appropriate, provide the necessary instructions.

How to request a return

Write to contact@grinfizz.com or use our contact form, providing your name, order number and the item you wish to return. For an issue, describe what happened and attach clear images where possible.

How to return the product

Returns are free. We will send you a label to attach to the parcel. Depending on carrier availability, we will arrange collection from your address or give you an address or drop-off point.

Pack the product securely and include the components you received. Keep proof of handover to the carrier. Do not send the parcel to the legal address in Wyoming: we will give you the return destination and the appropriate procedure.

Damaged or defective products

If the product arrives broken, deformed or with another defect, we recommend reporting it within 28 hours of receipt and sending a clear photograph. Failure to report within this time does not mean you lose your statutory rights.

In these cases, after verifying the issue, we offer a choice between a free replacement and a refund of the amount paid. If a return is necessary, we cover the costs and arrange the procedure described above.

Refunds

Once the product has been handed to the carrier and proof of drop-off is provided, we will process the refund without waiting for it to reach the warehouse. If we confirm that a return is unnecessary, we will process the refund after that confirmation.

We refund the amount paid for the returned items, taking account of discounts applied, using the same payment method. We charge no refund fees.

For statutory withdrawal, we refund within 14 calendar days of your notification; we may withhold the refund until we receive the goods or evidence of return, whichever happens first. The time for the credit to appear may depend on your bank.

Statutory right of withdrawal

Regardless of our 30-day guarantee, you may withdraw from a distance purchase within 14 calendar days of receipt without giving a reason, subject to applicable statutory exceptions. An unequivocal statement through the contact methods provided is sufficient; you do not need prior authorisation or photographs to exercise this right.

You must return the product within 14 calendar days of your notification. We will provide the label and free return arrangements. You are only responsible for diminished value resulting from handling beyond what is necessary to establish the product’s nature, characteristics and functioning.

Statutory warranty

These terms do not limit rights relating to lack of conformity. For new goods, the statutory warranty applicable in Spain covers lack of conformity that becomes apparent within three years of delivery, under the terms established by law.
