Considerations against the necessity:

1. Space Constraints: The Ninja BR201AMZ, with its large pitcher and base, 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 pitcher may be more than you need. In such cases, a smaller blender or personal blender might suffice.

3. Budget: While the Ninja BR201AMZ is not the most expensive blender on the market, it may still represent an investment depending on your budget. If you have budget constraints and do not require the larger capacity or extra power, you might consider more budget-friendly options.
