Review on Ethernet Shielded Weatherproof Internet Network by Terrance Castle

It matches my internet download speed in terms of signal strength. However, its length is not 25 feet; I was able to run it somehow from the router to my room. But that was a distance, and how do I know it's not 25 feet? Because I have a 25ft Belkin Ethernet cable and even had to tie that cable up because there was a lot of excess left over. Otherwise it serves its purpose.
