Review on Cables Unlimited 2 Outlet Xtender Power Cord Splitter: Streamline Your Power Needs by Robert Lemons

High quality, high quality, durable cable. Contrary to some other reviews, the load/neutral lines are correctly aligned in what I got. If you are concerned about the polarity of a wire, test it with an ohmmeter to rule out possible home wiring problems. Here's an easy way to check: 1) Plug the male end of the cable into one of the female ends. 2) Connect an ohmmeter to the other female end and check continuity between the neutral and load side. If there is NO continuity, the wires are NOT crossing and that side of the cable is fine. If there is continuity, then the lines have crossed and you should avoid using cables. 3) Insert the plug into the other socket and do the same (step 2), see above. If both ends are OK (i.e. NO continuity), the cable is safe to use.
