Customer Ratings & Reviews

I love these stainless steel blender cups for the Nutri Ninja. They hold up very nicely and are easy to clean. I like them so much better than the typical plastic Ninja blender cups because they don't scratch from blending ice and other ingredients and they don't look cloudy after a while from all of the scratches. Also, because they are stainless steel, they don't retain smells like the plastic cups do.

I needed coffee grinder, so I was going to purchase one from Krups which I had previously. I sometimes grind spices too, but the motor is connected with body so washing the krups was pain in the butt. So I was looking around, and found this one. It was cheap and the best part of this product is that I can wash this one with no worries! I gave four stars because I make espresso mostly and for espresso machines, burr grinders are recommended. This grinds particles to irregular sizes. If i run it for longer time (~70 seconds), It grinds to very fine powder, it's great for spices but not for coffee. I find grinding 30-35 seconds for 2Tbsp coffee beans (it makes double shot espresso) result the best with my espresso machine...

Definitely not as good as a burr grinder. I already had a ninja. This was smaller and easier to clean than a dedicated grinder. Works well enough to make coarse grind for my cold brew. Happy with my purchase.

I love it I use this on a daily bases, I use it for grinding fresh garlic everyday

It works really well. Only downfall is it cost as much as a normal spice Grinder, but with this you need to have the blender. This Grinder does not use a timer, you must press start and stop. It is super easy to clean

This is a nice addition to the Nutri ninja auto-iQ. I love having one base and multiple blenders, cups, food processor and now grinder. I've only used it a few times but seems ok. Haven't tried coffee yet.

I use it for my coffee beans to make my fresh coffee. Handles them no problem. Also good for making bbq dry rubs for you food.

The product is good. But I become more and more picky for coffees. So I decide to purchase a burr grinder.

Works great and fast. Quality is great. Works with my ninja iq

This easy & very efficient spice grinder was a perfect addition to our Ninja blender. While trying to find a decent spice grinder as we love to cook & mix our own spices, I stumbled onto this attachment to the Ninja. Easy peasy to use & clean.

There is nothing better in the morning than drink a coffee recently grounded.

This doesn’t work with blender. So please check your model. It’s not compatible with -BL770

I love the fact that I can use my Ninja Duo with so many great accessories like this one. I use it all the time to grind fresh coffee beans each morning. It smells so good!

I haven't used it yet but looking forward to it. It's small compact and easy to store.

I got this for flax seeds but also use it to grind my calcium tablets into powder to add to my protein shake. I'm going to try making peanut butter next.

I purchase this gift for a housewarming shower. It was great. We used it that night. Excellent for grinding whole coffee beans

Very good product but it didn't fit my blender so I return it. They should make more to fit most blenders models.

It’s very handy to use, I like fresh grind beans to brew coffee in the morning, and with this little grinder, it made the process less of a hassle.

This is fantastic! It grinds my coffee beans perfectly. I haven't tried spices yet. I have the Ninja Intelli Sense.

First let me say that this grinder seems like it is well made and sturdy. I have no doubt that it would have been a great product. However, Ninja has a real problem with compatibility of their accessories. This did not work for my Ultra-IQ blender even though my "series" was listed as compatible. I even called Ninja to confirm that I was not installing it wrong and customer support took about 15 minutes to research and come up with the same conclusion that it was not compatible.
