I love the protein shakes I can make that incorporate healthy greens but my NutriBullet leaks. If you twist tight enough, it loosens once you turn it on. If you don't tighten enough, causes an immediate mess. Great idea -- poor execution. I hate seeing remnants of former shakes in the bottom! Next time -I will bite the bullet (pardon the pun) and buy a Vitamix.
I love this gadget. My husband and I make smoothies daily, have since we bought it about a year ago. It works great, makes me wonder how we ever used a blender for smoothies. I even make salad dressing and cranberry slushies. Very easy to clean up as well. I haven't pulled the blender out of our cabinet since we bought it. Along with Vegan Smart powder, this little blender has helped me improve my health, with a healthy grab-and-go alternative that is no fuss. The only issue I ever had with it was user-error. I didn't close the lid tightly enough and some smoothie leaked out into the machine, making the triggers stick. I was able to clean it with a Q-tip and it's a tough little thing.
