Handy Tester
This works great to verify that all wires are connected and working. It will show opens, mi-wired pins, and shorted pins or wires. It cannot test that the twisted pairs are mated to the correct pin pairs but this is a minor issue since that is easy to check visually. You can use 2 short jumpers to test your premise wiring.
Great for Checking my New Home
My new home came with a central media center where all Ethernet and coax cables were terminated. I had five of each. They were not labeled as to which cable was connected to which room. Using this device, I was easily able to determine that and to confirm that all eight conductors were wired correctly. One room was completely disconnected and the builder fixed it. I used an RJ45 to coax adapter (which unfortunately Monoprice does not sell) to test the coax connections.
Perfect for my needs
I make up my own RJ12 straight-through and RJ45 crossover and straight-through cables for model railroading. This tester is simple but effective in this role. Verifies all conductors as continuous (or not) and that they are of the correct pin assignment (straight or crossover). You have to know what a crossover pin out should be, but a quick cheat-sheet and eventually your memory will be enough. For simple installations I can recommend this tester.
