Really like the sturdiness of the locking mechanisms. Using the Ninja junctions with cups almost every day for smoothies. Also like the lack of worries about it getting blocked or overheating given by the IQ functions.

Its the best blender ever. So powerful. Nothing else compares. Worth every dollar.

It works when others don't Just follow the instructions and it completes the job at hand

It is a great xhops the with ease

I am very happy with the Ninja Nutri Duo, I had a Nutra Bullet before, but it could t handle the frozen fruit, it packed it in after little use. This machine handles the frozen fruit to make awesome frozen fruit smoothies. Looks good on my kitchen bench also. Would highly recommend.

Just open the box to fine no user guides or recipie book inside. Called manufacture they said they couldn't send out one. Call Littlewoods they say they will send me it out let's see.

This is my second Ninja, upgraded to a newer model after re-gifting my first. This one is quieter, has more features and has larger containers for my large volume smoothies. Wouldn't buy any other machine on the market.

The smoothie blade started leaking oily, greasy stuff to our food. I contacted Ninja and told them. They didn't want to replace it. For a high end product like this, that costs a lot, it wasn't supposed to happen.

I am so pleased with this purchase. It has exceed my expectation. From the day we got it, we have been using it almost every day. It comes with three extra cups that have proved to be very useful. It makes smoothies like no other we ever had.

Love this product 5 star from me.
