I purchased the nutribullet pro from hsn several months ago, my husband and I enjoy making different types of fruit and vegetable drinks we are now able to get healthier drinks using the bullet we have not used as much fruit before the purchase for that it's been a blessing for us and our health.
May have used it four times before it started to leak and then the motor just shut down. I had to return it. Just cheaply made at a high price tag. I looked at other reviews, too little too late. Many have had exactly the same problems.
I like how compact this product is and how easy it is to use. Some times it is hard to get the lid off the cup as well as removing the blades. The cup kid has little corners that don't always come clean.
I bought the 900 over a year ago, after having used the 600 for over a year. I loved the 600 but after drinking two Bullets a day, it was getting tired and wasn't blending as well as when I purchased it. I bought the 900 and could immediately tell the difference. It blends more thoroughly and really cuts through seeds and stems well. The results are smoother. I have a tendency to fill it too full and the 900 still does a great job blending everything. I recommend the 900 when you are ready to replace your 600.
