Considerations against the necessity:

1. Space Constraints: The Ninja NJ601AMZ, with its large pitcher, may take up more counter or storage space compared to smaller blenders. If you have limited kitchen space or prefer a more compact appliance, this could be a drawback.

2. Personal Use: If you primarily need a blender for personal use or smaller servings, the 72 oz capacity of the Total Crushing Pitcher may be more than you need. In such cases, a smaller blender or personal blender might suffice.
