Huh, I've had much better luck, often buying from shadier places. I've bought a couple dozen cables from $CHINESE_RETAILER and they've all met the listed speed/power specs. I like to think I have an eye for spotting the passable items in an ocean of dropshipped sludge, but I'm not omnipotent. I do have an American brand that I'll order cables from if my money isn't paying for it.
