Review: The solution to a short monitor power cord - I bought a 31.5" ASUS monitor on a Prime Day last year. It's an excellent monitor - but its power cord is crazy short. I've never had a computer peripheral with such a short power cord. It wouldn't reach from the monitor - sitting of course on the desktop - to the power strip on the floor below. I grabbed a cheap extension cord that was sitting unused in a drawer, to connect the monitor to power. But I wasn't happy with how flimsy that cord felt. So I ordered this extension cord. It's the permanent solution to connect the monitor to the power strip. It feels more sturdy, and I like the configuration of the slimline plug.
