HDMI extender was sold as new. When it arrived, there was obvious evidence that someone had previously mounted the devices to a wall using the mounting ears (they were bent, and paint was scraped off by the screw heads). Further, one of the 5V supplies was dead (probably why the previous customer returned it). I replaced the supply with another I had available, and was able to make the extender work as advertised (that's why it got 3 stars instead of 0). Disappointed by the seller (which is the "Mirabox Official Store") for selling both used, and untested merchandise.
