What does the NJ600 warranty cover and how long does it last?

The NJ600 is covered by a one-year limited warranty against material defects and workmanship when used under normal household conditions. The warranty does not cover normal wear, commercial use, misuse, abuse, or damage from unauthorized repairs. If a defect is found, SharkNinja will repair or replace the unit, though a $19.95 return shipping and handling fee is required. (Page 6)
