I have 3 fidget cubes and I LOVE them! I have one at home, in the car, and at the office. Really helps me concentrate on something when my mind is all over the place. Not to mention I'm a natural born fidgeter so it's good to focus my energy on something. Best $9/each every in my opinion. The skin around my nails, lower lip, and eye lashes thank me for it because of them.
