Review on 🔧 Sduck 3" 6 Pin Rubber Blade Nutri Ninja BL770 30 BL771 30 BL773 30 BL774 BL780 30 Blender Replacement Parts - Exclusive for BL770 Series by Carnell Bollwitt

Not relevant to review but I had to replace this part for my Ninja because my stupid dog chewed the part that was at the time of purchase was supplied with the machine. (Don't worry, she was fine.) . (to the review) Beware of grandmothers and weakly armed people. Although a replacement part, it fits securely into Ninja cups (meaning they don't leak). The only reason I gave it 4 stars and not 5 is that the replacement part doesn't work as smoothly with the Ninja base as the original. I really have to "dunk" it when I rotate it to lock the cup in the ninja base. However, the price difference for this part versus buying the part from Ninja makes this minor inconvenience acceptable to me. If you lack upper body strength, this may not be for you.
