I like these extension cables & the variable lengths available. The quality is right up there with the rest of the well known cable manufacturers. In fact Momoprice's vendor quality exceeds some of the better known manufactures.
It's a cable, it connects the things it said it would. The price was right and the length was accurate. It took a while to get delivered but it was around Christmas and I chose the cheap shipping. If you want to pay a little and get what is advertised, I recommend it.
I wanted to have access to a USB 3.0 port that was only accessible on the rear of the computer. The 18" length is perfect for providing access at the side of the computer without being too long. As mentioned by another reviewer, the female socket is tight I echo the comment about making it less prone to inadvertent disconnects.
