POWER RACE sunglasses are guaranteed to the purchaser for a period of three years against defects in material or workmanship. DOLCE VITA reserves the right to repair or replace, in whole or in part, at its discretion, the POWER RACE sunglasses returned for repair or warranty and which are defective. The warranty does not apply to damages caused by improper use, accidental falls or collisions during normal sport activities, lack of reasonable care or misusage. The requests of replacements or repairs will be accepted at the discretion of the manufacturer. The three-year warranty only applies to frames, not to lenses (see scratched lenses). The guarantee is valid only with a proof of purchase carried out by an authorized POWER RACE dealer (example: receipt with date of sale). Alteration to sunglasses will void the warranty.
