Review on 🔪 6 Fins Blender Replacement Blade for Ninja 16 oz Cup - Compatible with Nutri Ninja BL660 1100w, BL771 30, BL770 1500w, BL780CO, BL663, BL663CO, BL665Q, BL740, BL773, BL780 by David Flores

Please don't waste your money. I have verified that I have the correct number of fins, that I have 16 ounce cups and one of the models listed in the description. I bought 2 of these to replace my original which had some tears. Both replacements had a different fit, which is why they didn't work in either scenario. In the image I've included, the one on the left emerges much further/can actually reach the bottom of the ribs below if it doesn't emerge that way when shuffling. The other one on the right will never reach far enough or get far enough. I couldn't even make a simple cocktail. I've run out of money and can't go back. I would give 0 stars if I could.
