Hi - thanks so much for the ideas! If you have the PopTech and C3 would you mind measuring the diameter for me? I don't see that in the Amazon listings.

Is the Poptech easier or harder to spin with one hand because of the shape of the spokes? I find that a classic spinner shape is easier to spin than the two I've tried so far.

Thank you so much!

Yes - this is the WeFidget I had... https://www.amazon.com/dp/B06XFBPB74 No jitter, no buzz, nothing. Felt like it wasn't moving at all when it was spinning. I thought I would like that but turns out I don't!
