OK, here's the scoop. The tester works great. It comes with a shielded patch cable. You can detach the bottom half for those long cable runs. It checks all pairs and shield. Most cables don't have shield though. It also checks for shorts, reversed, miswire, split pairs. And cross talk, but only at 3.5 Mhz, so if it fails that last one, you know it is pretty sucky cable. lol It's compact and tests everything in less than a second or two. Pretty fast unit. At this point I would buy it again. Oh, and the black carrying case that came with it has BK Precision embossed on the outside of it.
And someone is trying to hack my router right now. Doesn't that make you mad. lol again.
