Replacement Blade for Nutri Ninja Blender with Leak Proof Gasket and Sharp, Rust Resistant, Stainless Steel Blade, Precise Fit, 7-Fin Blade Assembly

Excellent.

This blade was so loud I made the dog stay out of the room when I used it for fear of damaging her hearing. Fourteen weeks after buying this piece of junk, the plastic under the blades over heated and deteriorated, filling the container with a vaporous head, befitting a mad scientist's lab, and spewing a blend of smoke and chemical stench through the air. Headed to the official Ninja site to buy the real deal.

It was too big for the BL770 Ninja Blender.
