6 Fins Bottom Blade Replacement for Nutri Ninja BL660 BL740 BL770 BL771 BL772BL773CO BL780 - Black

I only received one item. I ordered two of the same part. They don’t last no time. Starts leaking in weeks.

Worked perfectly to replace my old blade. Works well to blend my smoothies with frozen fruit and ice.Good quality and low price, I recommend this product to you!!

At first, the cup worked well and just like new. However, within a week, a leak started happening everytime I used it. And no, I was not filling it up beyond the max fill line. The seals on this cup are poorly made. Try to find an original one, that lasted me at least 2.5 years. I thought this would be better than 2 months

El producto puede ser bueno pero el modelo no calsa con el original almenos el que yo compre

This replacement blade saved me from buying a whole new Ninja system. It fits perfectly and came with a safety top for when not in use, which even the original did not have. I recommend it and would buy it again.

After little use, this liquid appeared under the base. Is that the contents leaking through?

it fits perfectly & I like that it comes with a lid, so storage is easier & I don't have to worry about cutting fingers while looking for something else in the same drawer.

I bought two of these and received them the end of July. It is not even mid October yet and one of them has already cracked and started leaking. The blades worked fine, but the plastic is not the best quality. I have it two stars because the blade had worked great. But it should only get 1 star for plastic durability.
