The blender works quite well. I have been using it almost daily for the past several weeks and it blends most mixtures excellently. Occasionally, it does leave thicker sections in the smoothie.
This wasn't a real negative to me but the recipe book that comes with it is a joke. It is more infomercial than recipe book but since I was buying it for blender I didn't really care.
I met with a nutritionist who said that I should incorporate more protein into my diet. She suggested a smoothie, to include vegan protein powder, within one hour post-workout. I tried using my blender, but it didn't breakdown the kale and frozen berries as much as I wanted, so I bought a NutrtiBullet Pro. I LOVE IT! My only wish is that I made this purchase years ago. My diet has improved tremendously, as I'm now getting a lot more fruits and veggies, as well as protein, and the NutriBullet is just so incredibly easy to use!
