If it is defective during the warranty period, we will repair or replace it free of charge. For in-warranty repairs, contact our Customer Service to learn the specific steps. We will do our best to solve your problems. All implied warranties on the product are limited to the duration of this expressed Warranty. Some states do not allow limitation on how long an implied Warranty lasts, so the above limitations may not apply to you.
