Blade Replacement for Ninja Blender 6 Fins Blade Assembly Replacement Parts for Nutri Ninja BL770 BL771 BL773CO

First, I can't believe the original blade on the Ninja only lasted for several months. This replacement is even worse. After every use there is a brownish discharge (large amount) even though the blades and plastic parts do not look damaged. I am sure this unhealthy and will not drink whatever we make when a discharge is released. Very unhappy. We bought a $30 Black and Decker for our smoothies. After reviewing all the negative comments on Ninja and their replacement parts, I'm disgusted and will make sure everyone I know hears about it.

It made our motor smoke too! I was coming on here to see if we were still within our return window. We were not. So, I'm leaving a review instead. It was not worth the purchase. It has negatively influenced our Ninja's current performance.

Made sure it would work with my Ninja model before buying. Every time I used it, it stressed the motor to the point of smoke! Will only buy OEM/Ninja going forward. Not a bargain if it kills the motor.
