Review on Pack Of 50 White Keystone Punch Down Jacks For Cat-5E RJ-45 Connections by David Perry

I almost never do reviews.These are junk. I have been doing Ethernet wiring for 20 years, and own an ISP. The RJ45 reciever has too much play within the jack, and do not consistently make a solid connection. If you wiggle your Ethernet cable you might be able to keep a connection, until someone breaths on it.I have tested with with a couple of manufactured ethernet cables, and my own made cat5 ends. Simply put the tolerances of the receiver on the jack are too great.This makes me have to re-do wiring for about 15 cable before I figured out they don't work. Very annoying.
