Overview
A personal-size blender from NutriBullet's Ultra line, sold here as an Amazon Renewed unit in gray, with a glow ring interface offering an automated smoothie cycle or manual pulse control.
The blending cups use Tritan Renew plastic made with 50% certified recycled content, and the blade is titanium coated stainless steel rather than bare steel. Because this is a Renewed listing, condition and included accessories should be confirmed against the seller's renewed-item terms before buying, since Amazon Renewed units are refurbished rather than new.
- Glow ring interface with two blend modes
- Tritan Renew cups (50% recycled content)
- Titanium-coated Rapid Extractor Blade
- Amazon Renewed condition
Who it's for
Suited to single-serving smoothie and shake users who want NutriBullet's Ultra features at a Renewed-item price. Not the choice for anyone who wants a factory-new unit with full retail packaging and warranty.
Strengths and trade-offs
Drawn from this product's published specifications.
- Automated smoothie cycle plus manual pulse mode
- Dishwasher-safe Tritan Renew cups
- Titanium-coated stainless steel blade
- Compact personal-size footprint
- Sold as Amazon Renewed, not new
- No buyer reviews yet to confirm condition or performance
- No seller description beyond the feature list
Performance notes
The power base lights up when a cup is attached, and choosing the full circle runs an automated smoothie cycle while the pulse circle gives manual control. The Rapid Extractor Blade pairs a stainless steel platform with a titanium coating, which the listing positions as reducing blend time and extending blade life.
