Replacement 6 Fins Female Blender Blade and 2 Cups with New Lids

In this review of the Replacement 6 Fins Female Blender Blade and 2 Cups with New handle Lids, the bottom line is simple: this is a practical, cost-effective fix for owners of compatible Ninja-style single-serve blenders who need the exact 6-fin female blade assembly. The reviewer found it most valuable for users who compared their original blade and confirmed the fin pattern matches the pictured 6-fin female design; when it does match, the stainless construction and redesigned screw lid address common issues like rust and leakage.

Key Features

• 6-fin female blade: The 4in 6-fin female design replaces worn or damaged blades when the fin pattern exactly matches the original, restoring cutting performance.
• Special stainless steel: The blade uses a rust-resistant stainless material and the seller offers a free replacement within three years in case of rust.
• New screw lid: The updated screw lid is designed to prevent leaks and keep the cup secure in a bag or during transport.
• BPA-free cups: Included cups and lids are made of Tritan material for clarity and durability and are dishwasher safe for easy cleaning.
• Compatibility guidance: The listing provides clear warnings about incompatible models and 7-fin or other blade sizes so buyers can confirm match before purchase.

Who It's For

This replacement is best for owners of Ninja-style Auto iQ single-serve blenders who need a like-for-like 6-fin female blade and who can visually verify the fin layout on their original assembly. It suits people who want to avoid rust and leakage with a blade that uses improved stainless steel and a redesigned screw lid.

Anyone using a 3.35in blade, a 7-fin blade, 16oz cups, or models explicitly listed as incompatible should look elsewhere; this product is not a universal replacement and will not fit a different fin count or those ss series or Nutri Ninja models named in the compatibility notes.

Pros & Cons

Pros

• Direct replacement when the 6-fin female pattern matches, restoring original blender function.
• Stainless steel construction with a three-year rust replacement promise adds confidence.
• Redesigned screw lid and handle lids reduce leakage and improve portability.
• BPA-free Tritan cups are dishwasher safe and durable for everyday use.

Cons

• Strict compatibility: must match the pictured 6-fin female layout or the part will not fit.
• Not suitable for many common Ninja and Nutri Ninja model numbers and 7-fin variants, which limits universality.
