Ordered 20 of these, all 20 tested very well for wiring order and resistances and Impedance matching.
Testing was done on a ByteBrothers Low Voltage Pro Model 3.
Impedance difference across pairs was usually about 1-2 ohms with 3 of the cables showing a 4-5 ohm difference. Certainly well within acceptable ranges.
I will be certainly buying from Monoprice again for my cable needs! :)
PROS: Gigabit capable.
Get to choose colors.
CONS: 2-3 of the cables I ordered are a little picky about being unplugged, have to squeeze the latch harder than normal. But as i rarely unplug my cables to move the devices I use, and rather that they are DEFINITELY plugged in, it is much less of a con for me. And I'm sure a quick light stroke of a small file would remedy this in a few seconds if it bugged someone that much.
