Why is this not standard on every fan...

Yes!! Why haven't anyone thought of this till now?!

where was this when my fan was on attack mode??

It shud be illegal not to put this on fans during manufacturing

I don't understand .. I don't have a fan though ^^

Usually the chains are just different lengths and not labeled, so its confusing to remember which one controls the fan speed or the light on the fan. Btw I have the chain things!!!! Its awesome.
