Replacement 4-Blade Attachment for Ninja Kitchen System 40 oz Bowl

The blade came right away and it works just great. I was amazedthat I was able to get a replacement and it works great.

Had the old one for about two and a half years did a bunch of ice, fruit and vegetables with it so not too bad. Not too much a fan of the whole ninja system but the blades work great and are very sharp. Especially at first.

This blade is alright. I replaced this on my ninja as the former blade picked up a pair of legs and got lost somewhere. (I am assuming it is hanging out with the socks that keep go missing from the wash) This goes in rather well, however, if I am blending something that has a little thickness to it, it kicks the blade up. I have to then stop the blender and push the blade back. This is quite an inconvenience, and it would probably attribute to the fact the blade may be slight too big for the grooves inside of the blender. Either way, good blade for the price. It cuts.

It replaces the blades that were missing and now allows me to return my ninja blender to an operative state, which is nice and allows me to avoid spending additional funds that would be needed with out these new blades.

Did not fit in my machine, no response from dealer

work great

Did not fit our current Ninja

This looks exactly like my ninja blade but this is much shorter so it doesn't reach the lid to stabilize. So gradually as you're using it it comes up and wobbles. Can't really use it. Not sure what ninja it's meant to fit since the rest is exactly right
