This item works out of the box, however, you must consider the application in which it is going to be used. I purchased this item to use with my Motorola Xoom and connect to the HDMI port of my HD TV, it worked perfectly. However after a couple of uses it broke under the weight of the HDMI cable and kind of loosened the mini-HDMI port on my Xoom. So if your going to use it in a light application or a static setup, it should be fine. For movement (games) and a large HDMI cable don't do it. The solution I found was a swivel adapter available at Radio Shack for ten bucks. The swivel allows the heavier cable to sit at an angle and not put strain on the plug at the contact point. Hope this helps. Going for the cheaper can turn out to be more expensive.
