We bought the 900 watt pro about 2 months ago. It is of the same quality as the 600 watt model we bought about 3 years ago. We are very happy with this purchase and would definately purchase another one.
Had the 600 power nutribullet and it was wearing down the extractor blade from daily use. I upgraded to the Pro and I am very happy with the power and the ease it churns out my daily smoothie
I purchased the NutriBullet Pro about a month ago and my whole family loves it! Its so easy to use and very easy to clean. Much more convenient to use than a regular blender. Now we make smoothies a lot more often!
I am so pleased with this purchase! I used the other for 3 years everyday for breakfast shakes it finally gave out lol. Much better quality the 900 series. Highly recommend the upgrade.
