Well I’m just pretty impressed. This is an affordable spinner and it behaves and has the quality of a high quality, much more expensive one. Very smooth spin, no wobble at all, very quiet. I was only able to take one side of the center piece out to check out the bearings, but they are fully enclosed on the side I was able to remove. Whether it was spinning on my finger or on a surface, it was a good clean spin that went for a good 2 minutes.
