The Ninja brand of anything has been a faithful friend of mine for awhile, it has never failed me yet. This includes the Ninja US - Ninja® Nutri-Blender Plus! It is great for smoothies! I happen to love smoothies but stopped making them for awhile. Now my desire for them has been revived again and can't stop having one smoothie at least three times per week! The process of just pressing down on the top part is so simple, no buttons needed. Two extra containers are also very handy to have for others in your family who love these smoothies. You can make other things as well, drinks and so forth. Clean up is a breeze. I am truly in love with this item and would never use anything else. You get all quality materials to use. Staying healthy and happy has never been so easy!
