I have had both version of BlendJet, and found it to not be as good as their advertisements make it seem (especially with blending leafy greens). I don't want to crunch any greens when I make a smoothie. I can do this same smoothie in my at-home Ninja blender, but I wanted to be able to take it on the go. This is perfect. Ninja power (but quieter!) in a portable container. The only downside is that it does drain the battery quickly, but I just have to make it a point to charge the battery every time I clean it.
