Excellent product with many different cups/mugs and an extra set of blades. I make a fruit smoothie every afternoon and this is the product to have. One caution: never fill the container above the MAX read on the containers. I even used a permanent marker to highlight this mark! Then make sure you have tightened the blades onto the container. Other than that you are ready to enjoy!
I upgraded to the 900 watts NurtriBullet Pro and I love it. The extra watts does make a big difference. I use it all the time. I have breast cancer and now my good nutrition matters more than ever. I even bought a second one as a back up because I never want to be without one.
