I use one of these to check the wiring of the USB cables I get, especially if I'm getting a weird one. I've always been a little freaked out by the story of that Google employee who posted very trusted USB-C cable reviews to Amazon, then got his equipment fried by one that crossed the wires.

But when I care about performance, I just get a cable from Anker and don't worry too much about it.

BUT THE MOST IMPORTANT THING IS: WHERE CAN I GET ONE OF THOSE TINY GREEN MILK CREATES IN THE PHOTO?
