Got these to help tame the mess behind my entertainment center. In essence, they work. They are simply velcro ties you can wrap around several cords, holding them in one, neat bundle. They aren't really meant for identifying cables,  but for holding several in a bundle. Because they work great, I can't give them less than 4 stars. $3 and change is pretty cheap, but if you wanted, you could do the same job with much cheaper products,  which is why I didn't give it 5 stars.
