This is perfect for using during work and meetings when I need to have something to do with my hands but can't be distracting.
This is a really lovely texture and feel (mine did start to squeak or something, make some kind of noise, but I'm pretty sure I could adjust it or contact folks here to figure out how to address that.) it's funny though, I got it partially because of how much I love massaging my hands with the "kid" ones (the purple roller is my fave), but I actually like that more than the knobs! We all have such different sensory preferences, and I really appreciate the range of options Ono offers in their rollers. My nephew prefers the weighty, heavy one and I prefer the light, soft one that's gentle on my hands' chronic pain and relieves tension, especially when I'm sore. The bumpy texture is going to be exactly right for someone else.
I bought one after I friend lent me theirs. My favorite fidget to keep in my bag or on hand.
I have the titanium Scroller. The weight and texture are quite satisfying. I used to fidget with my mouse and the Scroller simulates it well.
