The Fidget Cube was originally promoted on Kickstarter by Antsy Lab and then copied by many different companies. I'm sure the quality varies but the idea is the same. There are a lot of new findings of how fidgeting can actually improve your focus if you harness it.
In this video, I review the Fidget Cube with a quick run down of its sides and my thoughts. I generally enjoy the fidget cube but think you will like it dependent on how much you actually fidget.
