Nutribullet NB101B was non-functional. A cleaning of the actuator switches fixed it. Three drainage holes were unclogged. Now it works.
A friend gave me his Nutribullet NB101-B, a small blender used for smoothies. The blender was non-functional but intact. He said that the blender was well used, but started acting intermittently, after which it stopped working. There are many youtube vids on cleaning the blender, and the cleaning did fix the problem. There are, of course, extra details that I discovered.
