[Updated Version] 7 Fins Blender Blade Compatible with Ninja Blender Blade Replacement for Ninja Auto iQ BL682-30 BL642-30 BL450-30 BL482-30 BL687CO-30 ect.

Perfect replacement for the Ninja blender

Item arrived on time and does what it’s meant to.

I bought this replacement blade and didn't use it right away (a friend of mine had actually given me another blade to use). Once I broke this one out and used it, there was a smelly brown oil coming out of the bottom of the blade. It smelled like burnt oil; I could taste it in my smoothies as well.I tried to clean the blade, and let it dry thoroughly. It actually worked okay for about two blends, then it just started leaking everywhere, as seen in pictures. Leaked all over the inside of my blender. Do not purchase this blender blade, it is a waste of money.

I have ordered this product twice and both times, it fell apart within a couple of months. The first one developed cracks in housing after a few uses, which was one of the most common complaints. Afterward, I searched for other replacement products but came back to my original purchase to see the seller's notes that they have improved the product design to address previous defects. I hoped that the improved version would last longer but within a week, the steel cylinder that connects the blades to the rotor started rusting and kept spewing out the brown rusty liquid onto the blender. It's been two months now and we have hardly used this product 10-15 times, the blade unit has already developed cracks in the housing and a quick spin splashes rust/juice splash all over the place.

The washer is buried under the plastic and gets rusted within a few months and cannot clean/ change it.Blade is also not as sharp as my 5 years old blade which I've fixed and working well better than this.
