Yes but stating an item is covered by warranty, does not actually state what is covered, and for electrical items, they are pretty much worthless.  I dont even bother registering manufacturers warranties on electrical products, as virtually once you connect to a power source, the warranty provider will have a get out clause included and you are therefore left relying on good faith.  Don't get me started on extended warranties, would never purchase one.  Read one and you will know why.
