The folks at the fidget spinners news & reviews website Spinnermint.com took a closer look at Rotobow Nano and provided an independent in-depth review. The Nano was complemented on a small button style design with familiar "cigar holder" cutouts on 2 sides of the button, and a ridged, or tabbed grip aesthetic on the other 2 sides which presents a nice spinhold. It is offered in brass with a full ceramic bearing, it's a simple spinner with sophisticated spin possibilities.
Design & Aesthetics
We're dealing with a pretty simple brass body around a full ceramic bearing with threaded caps here folks. Nothing particularly novel about any one component, but they work well as a team for the Nano. The brass construction provides the necessary weight for this mini spinner, and the divots give you the spin points. At just 1.5" in diameter, it feels small in your hand for sure. Like a heavy piece of coin from the middle ages if we're romanticizing it. There are trade-offs here. Where the Rotobow Nano compact fidget spinner excels in spin grip from the divots, it lacks in finger preservation. Those grooves are sharp. And while no one spin is going to send you to the doctor, the cumulative effect of fidgeting can add up on your digits. Unless you have those addict calluses to protect you already.
The brass buttons sit above the body and have a slightly concave shape to them. They provide ample grip and the soft machine finish of the brass feels nice on the fingers. The full ceramic bearing comes with cage in and is easy to access for cleaning by removing the buttons, though I have not tried removing the bearing from the body.
