The Ninja blender's pitcher is only covered under the Ninja blender warranty if the product was defective. The warranty does not cover parts such as containers for standard wear and tear, as of 2015.
Pitchers that arrive broken, have malfunctioning parts or do not properly fit the blender base may be covered under the Ninja warranty for defective parts. Ninja's warranty ensures defective parts are repaired or replaced. A pitcher that is broken during use, worn down over time or lost is not covered under the warranty. Ninja blender owners can purchase blender replacement parts, including pitchers, at NinjaKitchen.com when warranty replacement is not an option.
