inspect any Product subject to a warranty claim to determine, at its sole discretion,

whether the claimed defect is a defect that is covered by the warranty. Note that Costou

regularly changes the models, colorways, and styles of its Products and cannot guarantee

the availability of an exact replacement for any Product. COSTOU DOES NOT ASSUME

its quality controls.
