^^^Yup. I teach high school and today was the first time I encountered the spinner in my room. I just about ripped it out of the kid's hand. It was distracting everyone around him (this wasn't a student who has ever distributed any indications of ADHD or distractibility or fidgetiness himself; I think he just thinks it is cool.) As a teacher, I much prefer the cubes that they can hold in their hand unobtrusively without anyone really seeing them.
