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 Threlkeld Drauch

It appeared to be made at a good price and it was in stock for quick dispatch. I rated it good 2 months ago as it started well. then it ended very badly. 60 days later: - The o-ring that prevents the cup from leaking kept falling onto the base of the blade and my wife was VERY fed up with sharp blades and the o-ring constantly reinserting it back into the base of the die Blade. the blade base.- Then the seal between the gear and the mixing blades failed. So black fat drops were added to the smoothie. not good. Ball bearings and shards of metal ended up in the bottom of the blender, and some bits and fat ended up in the smoothie. see drawing. (Gears/blade assembly wobbles about 1/2 inch, gasket and ball bearings missing) I went back to the kitchen ninja and bought a "genuine" replacement for a bit more. Knowing where the defect is located makes it easier to identify the quality in the original part. If you bought any of these products based on my original recommendation, I apologize. I took photos today and posted them along with this review so you are updated on the quality of this product. We've been doing 3 shakes a day since June 15th, so 60 days / 180+ uses and no luck. The teeth on the blender and base are still badly worn, so I think that's how the ninja works. So ninja, love their blender aside from the wear and tear on the gearing between the base motor and the cup blade attachment. The Sduck spare part is scrap. and potentially the dangerous consequences of chemical spills.
