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 was expecting to love this and have it last long, especially given the cost, but it’s really just okay. The top and bottom screw out if you hold them with your pointer or middle finger and thumb to spin. They look like they should only screw out with an Allen key, but I frequently end up doing it with my fingers. I find that rather than helping with focus it’s more of a distraction I sit with and think, losing time. It’s heavy so if it rolls off your lap, desk, or couch it can chip/scratch hard floors. Heads up! Bottom line: not worth the price!

Perfectly smooth and perfectly silent.

I got the Jr size cause I have kindve smaller hands and it doesn't overwhelm my hand, and fits really nice in my pocket. And it's soooo satisfying, I had my family try it and now they want some too lol

Luv these products! Purchased three and there are times when all of the clients in a family session are using them. Hopefully, I'll be able to afford a few more tea accommodate client preferences in the near future.
