Totally helped with my focus and it fits right in your pocket! I was skeptical that this thing would work but when I do anything that requires me to focus, this helps keeps my attention! One thing that could be improved is the joystick, needs to have a little more leverage because it’s hard to move it around. The part that has the batman logo which is some kind of “worry stone” could be replaced with something too because it really do much for me. Love the design though, I’m gonna get more so I don’t have to bring the same fidget cube everywhere I go.
