Although it's not required by law in the USA to register your product in order to receive support under the warranty, it simplifies the process if your product is registered. It also gives the manufacturer a way to contact you if a recall is issued in the future. Sometimes they even throw in a bonus to reward those who do register their product, although I don't think that's as common anymore since the economy went belly-up and started floating at the top of the tank. I once got free rubber impact bumpers for my labeler when I registered it. Note that you only have to provide your name and contact information along with relevant product information (serial number, etc.) when you register your warranty. The marketing questions (age, salary, etc.) are optional.
