Often warranties are fairly specific and only pertain to the original purchaser and are non transferable. Dependent upon which state you reside in your rights as a consumer under a warranty may differ greatly. Most manufacturers will repair the product as long as the person filing the warranty claim can show proof of purchase along with the serial number. Many items can be traced by the serial number as to the exact date of sale and the warranty period starts from that date. Its always best to check with the manufacture to see how they handle warranty claims especially if your product was received as a gift. While most manufacturers back what they sell without ever questioning the claimant, there's always those few people who try to pull a fast one on the manufacturer and that will often cause the process to not work as smoothly for others.
