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 recently bought this item to help make my smoothies. I was a bit sceptical about spending the money for this product and was going to get something cheaper. I changed my mind because I had bought lower wattage blenders before and they have all broken down leaving me without a blender and out of...

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.

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.

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.

Love this product 5 star from me.

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.
