I've bought the steel roller and it's very good and has a good weight. It's smooth and silent and rolls very good. I just like it a lot.
We have the metal Ono and the foam one and they both roll so so smoothly! They just glide in your hand. We all prefer the metal one, even the kids. The weight is grounding and I like that it gets cold, room temperature cold or you can put it in the freezer and you get that extra sensory input. Also the rolling is completely silent and the feel good if you massage your legs with them. Buy one. Or several. You won't forget it!
I wish I had an ONO when I was young! But I am so grateful for it now. For decades I didn't realize my fidgetiness was actually stimming. As a self-diagnosed Neurodivergent adult having a productive way to release energy (and save my skin) is miraculous! Thank you!
I keep the steel at home. 12 oz is too heavy to carry around. I like the weight. If your hands get clammy at all you might not like the feel of this one as it heats up from your body heat. Regular one doesn't seem to have the same issue.
Can also be used to regulate. I'll roll really fast and then I notice and can slow it down and that slows me down too.
Helpful in therapy when doing more intense work. Helped keep me grounded instead of dissociating.
