We warrant our products to be free of defects in material and workmanship for one year from the date of

unauthorized service, or incidental or consequential damages beyond Davis products themselves. Implied
warranties are limited in duration to the life of the limited warranty.
Some states do not allow limitations on how long an implied warranty lasts, or the exclusion or limitation
