Review on StarTech.com GC98FF Black DB9 to RJ45 Modular Adapter - Serial Adapter for Female DB-9 to Female RJ-45 by Eric Williamson

Worked well for its purpose but due to the plastic housing covering the metal connection it didn't fit snugly on some connectors to be able to attach. I had to buy an adapter cable to plug it in between as the TV I needed to connect to also had a plastic housing next to the plug that prevented it from screwing into its pins because it wasn't close enough. Overall, however, the contacts and build quality are good.
