In the beginning this was amazing, way louder than I've ever heard but it's a blender so no biggie it won't be on for over 45-60 seconds (I do recommend planning ahead so nobody is sleeping while using) At almost 4 months ownership I noticed constant leaking. It started subtle and you couldn't see it from the outside but had to wipe clean after every use so wouldn't go into motor. And then it started to spray! Like covering myself and walls kinda spray. Attempted to change seal nothing and then to top it off one day it sprayed excessively and started to smoke!! P.S. Company doesn't honor warranty as it claims and they're never at fault it's always the our fault.

Was to loud, sounds like an airplane taking off.

Truly awesome! It works so well that I ordered an extra one and send it to my mom

Threading the blades onto the cup is totally frustrating! At times it keeps running even tho it isn’t automatic...returning it.....

Love this thing! It's such a huge upgrade from my old school blender. So fast, easy to clean, helping me eat better!

This is a great blender to make healthy drinks for the whole family. Comes with two beverage cups. Great price too.

This is my second ninja…Makes perfect smoothies for breakfast! The newer model is quieter than my first… Love it

I have used this twice a day. without any problems.. love the drinks i can make with the nutra ninja. I have even made some of my own.

Love this thing it works great its the perfect size, now I can easily make smoothies every morning and its easy to clean.

after I bought this Nutri Ninja auto iQ, and tried, it is fantastic blender, very convenient for breakfast drink, and health, I will recommend this to my friends, actually I did already.
