I am obsessed with this thing. I saw it on sale at target for $15 and figured it was worth trying. At night, I fill a sandwich sized ziploc bag with fresh fruit and put it in the freezer. In the morning, I drop the contents into the blender and add about a cup of almond/coconut/dairy milk and sprinkle in some protein power (Spirulina)... then blend! You have to take the lid off and mix contents some to make sure everything makes it to the bottom, but I can't believe how powerful the little motor is. The cleanup is easy too, all you have to wash is the cup on top which is no more difficult than rinsing out a standard drinking glass. Great find!
