1-pack Extractor Blade Assembly 7 Fins Ninja Blender Blade Ninja Blender Replacement Parts Compatible with Ninja Blenders Auto iQ BL480 BL482 BL642 BL682 NN102

Bad quality, after couple of uses it starts to leak brown colored rust or liquid to the food item.

It’s terrible quality. In less than 3 months it’s already leaking and giving out browning to all the blending. And makes noise too much now

This product while appears like the original its has a very dangerous flaw. I noticed after few weeks of use one the second wash with only water that brown liquid (could be the glue or the seal) is leaking from the bottom and then it started to leak inside the mix. I have immediately dispose this product and will not recommend it to anyone. luckily am only using it to make shakes so I noticed the wired color.

works ok for a couple of weeks or so and then reverts to making a really loud noise when blending!

The plastic melted by rotation heat, its oil comes out from both sides up and down, plastic melted in food, the base opend during rotation and fly up

Hasta ahora funciona muy bien con nuestra ninja CT680

I love my Ninja Blender so much. I make a protein shake every day, one with plenty of ice cubes and sometimes fruits and vegetables. The higher watt motor of the Ninja makes it all work perfectly. But these dang blender blade assemblies don't hold up. I imagine the problem is the amount of torque exerted by the 1500 watt motor. The black plastic that holds the blade in place always develops cracks, and then my protein shake starts sneaking through those cracks as it is being blended. Also, the blade element gets a little bit loose, which allows some other leaking. I've tried tightening it (it's tricky because you have to do the opposite of what feels right). Most of these assemblies last me less than 6 months, including the one that came with the blender and was (I assume) made by Ninja. Still, buying a new one of these every 6 months or so is cheaper than buying a new blender. It comes with a gasket that slips into the depth of the threaded part and should help prevent leaking - it does, but only in the part it is protecting. That gasket can't do anything about leaking through cracks in the plastic. I believe that, although the blades are quite sharp, the real work of blending happens through the creation of cavitation pockets . . . that takes a powerful motor.

Used it today, worked great.

Bought this to replace my previous 6-year old Ninja blender blades which started getting stuck. I’m happy with how well this works, didn’t have any problems, no installation required.

Ótimo, atende as expectativas
