Definitely shows the original strength of my blender when I first got it Review: Great Ninja Blade Replacement - I was hesitant to order this Ninja replacement blade, worried it might not fit properly or be substandard—but I’m so glad I took the chance. It arrived quickly, and when I compared it to my original blade (see photos), I noticed it was slightly heavier with a bit thicker blades, but overall it fit perfectly and matched the form of my old blade. I washed it, rinsed it, and used it right away to make my matcha tea with boiling water, milk, MCT oil, fiber, and protein powder—and it worked flawlessly. My old blade had been leaking and making alarming noises, so this new one put my mind at ease. The only hiccup was a faint plastic taste in my first batch. I gave the blade a long soak in very hot soapy water and washed it thoroughly, and the next batch was perfect. My advice: be sure to wash the new blade well before first use to remove any residual plastic taste. Overall, a solid, reliable replacement that is extending the life of my Ninja blender! ## Features - Compatibility: Blade assembly diameter 3.35"/ 8.5 cm. 6 fins blade compatible with Ninja BL660 (1100w), BL770 (1500w), BL740, BL663, BL663CO 30, BL665Q, BL770W, BL771, BL771C, BL772, BL772Q, BL773, BL773CO, BL780,BL770 30, BL773CO 30, BL771 30,BL780 30, BL780CO 30.
