Satisfaction Guarantee

30-Day Satisfaction Guarantee

At Exo Athletics, we stand behind our products and quality controls. If for any reason you are not satisfied with a Massov® product you purchased from us or one of our authorized sellers in the United States, you may request a refund or replacement product within 30 days of the date of purchase.  Please note that because we are unable to control the quality of our products sold by unauthorized sellers, unless otherwise prohibited by law, the Guarantee is not available for products purchased from unauthorized sellers, including unauthorized internet sites. The Guarantee is also limited to original, end-user purchasers in the United States.

How to Submit a Claim

To submit a Guarantee request, please contact us at and have information available regarding where and when you purchased your product. You may also be asked to provide proof of purchase, submit photos of your product or its packaging, mail your product to Exo Athletics, or provide other information to assist Exo Athletics in processing your request. You must submit your Guarantee request within 30 days of the date of original purchase.

Guarantee Guidelines

Exo Athletics reserves the right to verify information, require a valid proof of purchase, and to deny Guarantee requests in its discretion in cases of suspected fraud or where Exo Athletics concludes that the purchaser has abused the Guarantee. Exo Athletics may amend or terminate the Guarantee at any time without notice.
