I purchased this in late August 2014 and began using it for my daily lunch immediately. It has been able to handle anything that I have put into it, pulverizing raw carrots with nary a problem, not even a change in the motor sound. I am already recommending it to many people. (I bought this because our daughter has a 350w Cuisinart smoothie maker, and it labors a bit. Mine breezes through anything.
I bought it a few months ago and truly did not know what to expect. I have juicer that I used a couple of times a put it away.It was a choir to clean and to store and to many parts. The Nutri bullet is easy to use and reuse again with.Its compact and stores nicely
I love this machine. The only issue is the gasket used in the lid. This becomes dirty pretty fast and needs to be removed and cleaned. But once you pull it out to clean, then it doesn't seem to fit properly again and leaks occur around the seal. Need to figure a better sealing mechanism. I use my machine daily to make smoothies. Haven't tried any other use for it, but it grinds up frozen blueberries and walnuts to make my smoothie.
After using a juicer for 13 years and dreading the cleanup each time I decided to try the NutriBullet PRO. What a difference! Easy to clean and makes some good tasting, good for me drinks.
