@saxnot There isnt much of one.. the only practical use as i said is 1) you can switch out the tips from usb-c to micro ot whatever and 2) the panties women will throw at you when they witness how cool looking your usb cable is.
I bought it mostly to get laid, so #2
People buy them because they look cool, have some minimally practical purpose, and are very thick and sturdy, very well built, and they look cool attached to a nice keyboard.. Its mostly a waste of money, and I knew that going in, but having a cable that will actually last a lifetime is a nice change regardless.
