Review on Cable Matters UL Listed 10-Pack RJ45 Keystone Jack - High Quality Black Connectors for Ultimate Connectivity by Robert White

I feel guilty giving them 4 stars instead of 5 because this is my first time using Ethernet Keystone and I'm not sure if my complaint is specific to this Cable Matters Keystone Cat6 or I'm the same Problem would have with every brand. I complain that four of these didn't fit the Leviton Decora 4 port wall plate because they were too wide. Everything else about them was positive. I'll admit there wasn't much room in my two post box so I had to stuff some Cat6 cable behind it. After installation I checked the continuity of all the keystones and they all worked.
