The lids do not securely fasten which makes drinking from them difficult. You almost always have to transfer it into another shaker. The travel lid you may as well toss out. Everyone says the same thing - leaks from everywhere. Cheaply made.

I received for my B-Day in March 2014 and by November 2014 the plastic tabs that you push down on will not move freely making it difficult to use. Very disappointed!!!

I have had mine for several months now. I still love it and drink a delicious super nutricious smoothy every day. My body instantly feels better and it is a TREAT !

I purchased the series 900 nutribullet from the Best buy 9 month ago it is already broken. I can't get it to turn it's lock in place to blend. I have had to go back to using the original. Very disappointed.

I just made my first smoothie with it and it's delicious. It's probably too early to post a review, but it was so easy and tasty that I came back to the website to buy some more cups to hold my future smoothies :D

I bought this a month ago, and sometimes it works and sometimes it doesn't...I have problems with not being able to twist off the container from the blender frequently.

I'm inspired to juice more and make smoothies because not only is the Nutra Bullet easy to use its also so quick and easy to cleanup. I even travel with mine on long trips.

I' ve had this for a while, and I can't live without it. It makes breakfast easy and fast in the morning. I also use it at dinner time. I'm getting so many nutrients without even knowing it!

It took just days to feel the rejuvenating effects of bullet smoothies. Most of all THEY TASTE GREAT .. Three friends have bought the bullet since I raved about it and all are pleased.

There are two features I really like about this: 1) truly easy to clean so I use more often 2) can grind up carrots easily when I add them to my mixture
