By improving its design with 1200 watts of power, an easy-to-use illuminated interface, and increased blade durability, the Ultra takes the core of the beloved Nutribullet® and makes it even better. It is our quietest single-serve blender to date because it is designed to produce sound at a lower frequency than earlier models, and its TritanTM Renew blending cups add sustainable strength to the table. It is powerful, elegant, and consistently produces blends of the highest caliber.
