Waaay better than the crap on Amazon

I was skeptical at first that I was paying more for another low quality blender blade, but this one seems to be the real deal. I had bought 2 from Amazon, and after about a week there was grease leaking out and after a month or so it doesn't even spin freely anymore. I've had this one over 2 weeks and it works as well as when I got it. I'll update if that changes.

True Ninja Blade

Correct OEM product. Other places sell the cheaper and less quality than this one. This is thicker than some of the knockoffs.

Works great, ordered in a pinch when my current lid cracked and was leaking. Genuine ninja blender top/blade, fit perfectly.
