These are great for keeping your cords from laying all over the place. At any given time I can have 3-4 cables laying on my desk and they inevitably fall to the floor, well with these I no longer have that issue.
They secure very tight to the desktop and have two different sides to the clamp, so it doesn't matter if you have a thick or thin desktop, this will fit securely.
They also hold all of the cables I have tried from thick, thin, flat or round.
