Terms of Use

30-Day Money-Back Guarantee for Any Reason

Undamaged products may be returned for a full refund for any reason within 30 days of the date of purchase. Once the returned item arrives back in OSTO’s warehouse for inspection, the refund process will begin.

• Items must include original packaging.
• For non-quality related warranty claims, the buyer is responsible for shipping costs, and OSTO refunds the cost of the product itself.
• Returns may be rejected if items do not meet the above requirements.

Refund requests for the 30-day money back guarantee expire 30 days after receiving the product. It is not possible to process a request for a refund for non-quality issues for items that have expired this 30-day window. For purchases not made directly through OSTO’s online stores, please contact sellers for refunds. For quality-related issues, please see below.

How long does it take to get a refund?

Refunds will be issued once the item arrives at our warehouse. The refund will be credited back using the same method as when your initial order was made. Processing time typically takes 3-5 working days.

Warranty Claims for Quality-Related Issues

If you have any quality-related problems with the products received, please contact us to solve them.

OSTO's limited warranty is restricted to the country of purchase. The limited warranty is void on items taken outside the country they were originally bought in or shipped to directly from an authorized online purchase.

For quality-related warranty claims,  items will be replaced with new products of the same or the same value. In situations where a replacement is not an available or preferred option, OSTO will offer a partial refund according to the usage time of the device.

Warranties on all replacements follow the same warranty timeframe of the original defective item, or 3 months after being replaced, whichever is longer. Warranties on products are void after having been fully refunded.

Process:

• Buyer must provide sufficient proof of purchase.
• OSTO must document what happens when buyers troubleshoot the product.
• It may be necessary to return an item for quality inspection or failure analysis.
• For defective items that OSTO needs to have returned, warranties on those replacements are voided if the wrong item is returned to OSTO or if the defective item is not returned.

Valid proof of purchase:

• Order number from online purchases made through OSTO
• Sales invoice

Please note that more than one type of proof of purchase may be required to process a warranty claim (such as receipt of money transfer and confirmation of address item was originally shipped to).

It is not possible to process a warranty claim for items that have expired their original warranty timeframe.

Shipping costs must be covered by buyer in the following situations:

• Warranty claims on items taken outside the original country of purchase
• Returning personal items
• Returning items claimed to have defects but found by OSTO quality control to be in working condition
• Costs associated with unauthorized returns (any returns made outside of the approved warranty process)

Not Covered Under Warranty:

Products without sufficient proof of purchase

• Items that have expired their warranty period.
• Free products.
• Damage from outside sources.

• Purchases from unauthorized resellers.

When returning items with a prepaid shipping label provided by OSTO, OSTO takes responsibility for any damage or loss incurred in transit. When returning items for non-quality issues, the buyer assumes responsibility for any damage or loss incurred in transit. OSTO does not provide refunds for items damaged in transit for non-quality related warranty claims.
