NutriBullet replacement parts are covered under warranty, as of 2015. This assumes that an individual part is the cause of the appliance not working properly and that a replacement part is available. Otherwise, the entire NutriBullet may be replaced.
The NutriBullet comes with a limited one-year warranty. It stipulates that if the appliance stops working to satisfaction due to defects in workmanship or materials, it will be repaired or replaced for free. The purchaser, however, pays for shipping and processing. Various conditions affect the validity of the warranty. These include that the appliance is only used for consumer and not commercial purposes, and that proof of purchase can be demonstrated.
