Are fidget spinners dangerous?

I saw an article the other day that claims fidget spinners are dangerous because someone seriously injured himself with one. How did he seriously injure himself? He did it by using an air compressor to spin it faster than it was designed to spin.

Right. That is totally because the product itself is defective. Sure.

When you use a safe product in an unsafe way, you get hurt. That is your fault and your fault alone.

Idiot.
