The rounded edges really do make it comfortable to hold for long fidget sessions, and the hollow jellyfish shape gives it a surprisingly balanced spin that's hard to put down. I've been carrying it everywhere since it arrived, and the minimalist look gets compliments from coworkers every time.

The hollow cutouts catch the light in a way that makes it look like it's floating while it spins. Edges are rounded just right, so it's comfortable to hold even during longer fidgeting sessions.

Spent a whole lunch break just flicking this thing, and the hollow jellyfish body makes it light enough to keep going without my wrist getting tired. The round edges slide through my fingers way smoother than my old metal spinner.
