Warranty Claims for Quality-Related Issues

All quality-related defects on items sold directly by XMCOSY+ or XMCOSY+'s authorized resellers are covered by an extensive warranty, starting from the date of purchase (see top of page for your product’s warranty period).

XMCOSY+'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.

Quality-related warranty claims purchased through XMCOSY+'s Authorized Distributors and Retailers (such as Walmart and Costco, Bestbuy) are handled post-sale by the respective distributors and retailers.

Warranties on all replacements follow the same warranty time frame of the original defective item. Warranties on products are void after having been fully refunded.


  • Buyer must provide sufficient proof of purchase
  • XMCOSY+must document what happens when buyers troubleshoot the product
  • The defective item’s serial number and/or visible proof depicting the defect are required
  • It may be necessary to return an item for quality inspection
  • For defective items that XMCOSY+needs to have returned, warranties on those replacements are voided if the wrong item is returned to XMCOSY+or if the defective item is not returned.

Valid proof of purchase:

  • Order number from online purchases made through XMCOSY+.
  • 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).
