After many replacement blades on my 1st model of the 600 because of leakage, my 600 died at about 2 years of age. The inside had rusted screws and much grunge from the leakage. I took a chance thinking Nutri Bullet must have surely made improvements since my first purchase and I bought a 900 only to be very disappointed within 1 week, by the same problem of leakage which means this one will also die before its time if I don't throw it away first due to extreme frustration of having it leak so much, making a mess that leaks into the machine. I have to turn the machine upside down stuffed with paper towels to help it dry out. Aside from the horrible messes I end up with, the 900 has good power. but this is so, NOT right...
I bought my Nutribullet over a month ago and use it a lot. It took me a few tries to be comfortable with the amount of food used as well as liquid. I am anxious to see if it will replace my blender for other uses.
I got the nutribullet pro as a gift a little over a month and I'm enjoying it very much. I make smoothies all the time. It's easy to use and its quickness is amazing.
I bought the NutriBullet Pro after careful research / comparison (primarily looking at features, motor power, and cost. I thought I had found the perfect match. It leaked and made such a mess in the base I just could not stand the disappointment - I returned it within less than a month.
