Let me guess...
Nobody measured how many G's you can apply over electronics housed in fidget spinners.
I wouldn't be surprised if it went above 100 G. Electronics that are already prone to burst into flames even when they are not submitted to higher degrees of acceleration, are now regularly submitted to several thousand RPM for, let's say, 60 seconds at a time. What can go wrong?
Unless they are housed in the static center. I hope so. So we are dealing just with cheap Chinese components.
Only SD cards that I heard are certified to survive 1000G acceleration, by the way.
