Review on Efficient Networking: VCE 25-Pack Cat6 RJ45 90-Degree Keystone Jack Insert, Black Ethernet UTP Cat6 Keystone Jacks (UL Listed) by Philip Brianne

I'll give some others a positive review - I don't like the cable layout. Beyond that though, they're incredibly solidly built, especially for the price. Some cheaper jacks save two rear brackets and often break if you deviate even a little. But these things are reliable. Writing this review after purchasing the second spool after the first spool was just what I needed. A very happy customer.
