5-piece Blender Cups Replacement for Ninja Single Serve 16oz Cups with Sip & Seal Lids, 6 Fins Extractor Blade Compatible with Ninja Blenders Pro BL660 BL663 BL663CO BL665Q BL740 BL770

Exactly what I needed!! Replacement cups for my Ninji Blender. Fits and works as it should. Lid don't leak. I like having a couple of extra to rotate out and for multiple users.

These cups fit better than the cups that came with my NINJA. I’m sure the original cups are defective because the original blade top is too big for the original cups. When these EQUUST replacement cups came, the first thing I did was to screw the blender top on to each cup- effortless. Then I put them both on the blender base. They work perfectly. I have NINJA PROFESSIONAL 1500 Watts Model BL770.

Nice cups but it Doesn’t fit the Ninja Pro

I have gone through several of these cup and blade kits. It is NOT worth the time and mess. They never last more than a year. My last one lasted like four months before it started leaking. I ended up throwing away and buying actual ninja replacements.

I ordered this set on Friday 10/3/25 and received it today 10/4/25. The packaging was good. The set had its own box with all the contents tightly packed and individually wrapped and that box was placed into another box. I cleaned the everything with mild soapy water then proceeded to make my favorite protein shake. Hoping for no leaks or no weird functioning blade movement. Happy to say the quality of the stuff is great with the cup, blending portion, and sip lids all sealing very well. The value for the money spent is good since everything works! This kit worked seamlessly with my NINJA BL770 30 1500W blender.

Works great

This fits my ninja blender perfectly. Great value

Works well with my Ninja. But plastic is not the same quality by any means.
