The warranty terms for products purchased from different retailers can vary. You need to contact the retailer who sold you the product in a warranty case. If you have ordered the product directly from iSocket Systems, we offer at least one year full warranty from the date of purchase. If you experience a fault, please contact us. We aim to give you full satisfaction when dealing with warranty! That is our advantage in compare with no-name sellers or corporations who don't care after they sold the product to you.
