Should you register that new product?
It's not necessary to fill out a warranty card or register your new product online to guarantee a warranty.
A sales receipt or proof of purchase is all that is required to file a warranty claim. Valid products are automatically covered by a limited warranty (the usual type) and there is no need to submit your details to the manufacturer.
For warranty claims, please contact the retailer where you purchased your item along with your sales receipt or proof of purchase, the retailer will in turn provide details to the manufacturer.
