I ordered Cat 6 cables 550MHz, when I received the product the box was labeled 500MHz by the manufacturer. The printing on the cable cove is labeled as 550MHz. The product arrived in a timely manner. I contacted customer service and sent photos of the box. Monoprice offered to send a pre-paid shipping label for a full refund.
PROS: Exceptional customer service, made an effort to make the customer happy.
PROS: Pretty much what I expected. I like the length remaining countdown on the cable so you know how much has been used. It makes it easy to know how much is left in a box.
CONS: The center insulator is not perforated. In some of the higher end cables it now comes ready to snap out. It makes it easier to remove without having to cut it out and allows you to get the cable farther into the clamshell
