I started a new office for which I was looking for waterproof heavy-duty Cat 7 cable to set up a network. On the recommendation of one of my partners, I bought this Ethernet cable. I must say this Ethernet cable is 650 ft long worth buying. It was surprisingly easy to fish through a long stretch of underground conduit with a couple of reasonably tight turns. The solid conductor is super easy to work with and seems very durable. It has a larger diameter than cat6 cable, so it becomes difficult to connect RJ45 connectors. The transfer speed is fantastic. It is well made, and the shielding is excellent. Overall it works, and the size of it is correct to its specifications.
