I have been using my new Ninja Blast personal blender everyday for the past 2 weeks and I am so delighted with it! It is so convenient and easy to use. I make different type of protein shakes everyday so I have used my blender with all kinds of fruits and leaves, ice and nut butters and every single time my shake is perfectly blended, even when I add ice! . It is a breeze to clean and very practical to carry around. I just traveled overseas with it and made my life so much easier!
