The O2 Air & Sea Warranty is 1 year from the date of purchase.
The manufacturer warrants all products to be free from defects in workmanship and materials, under normal use and conditions, for a period of one (1) year from the original invoice date. This warranty is non-transferable and will be void if the main unit has been opened or tampered with. Shipping and handling fees are to be paid for by the customer. During the warranty period, the manufacturer agrees, at its option, to repair a defect in material or workmanship or to provide a repaired or refurbished unit in exchange without charge (except for a fee for shipping, handling, packing, return postage, and insurance which will be incurred by the customer). However, any repair or replacement is subject to verification of the defect or malfunction, and proof of purchase must be provided by verifying the order number in the original customer email or receipt.
