I got them a few days ago. Left one is the Wangyue rainbow spinner ($5.80) [https://www.amazon.com/Wangyue-Spinner-Collection-Fashion-Rainbow/dp/B06XYHQBZ5] and right one is a crappy clone of the Apsung copper spinner. It was only $3 (also on Amazon) so I thought I'd give it a shot.

Here's a video of them together: https://youtu.be/avprecef7Wk

I actually like both but for different reasons. The black aluminum spinner spins quite smoothly and is super light. It's a joy to 1-hand spin.

The rainbow spinner is heavy and gives a really good gyro effect. I don't use it often because of the weight but the light reflection while spinning is beautiful. I'd say even better than my LED spinner.
