My corded eyeglass retainers are always getting hung up on my clothes, jacket, or even the chair I'm stitting on.  I don't have that problem with the Cablz retainers.  My only complaint is that 14 inches is probably a bit too long.  Much shorter than that and it might be a bit more of a chore to put your glasses back on when hanging on your neck.  But when I try to lean back in my chair or when I'm wearing a jacket with a hood, whatever I lean up against pushes against the Cablz and forces my glasses off my face.
