Very good quality cables. The wires are good solid copper wire, the foil used to wrap the pairs is good thick foil. The wire mesh isn't as dense and thick as in the photo and is actually very loose and sparse, but I think the thicker foil on the twisted pairs makes up for that. The outer coating is also thick, which is good for durability but also makes it harder to bend in tight spaces, but I think if you're buying this type of cable, you probably expect that. As a bonus, the wooden spindle that my cable ran on makes a nice sturdy table stand or chair.
