I have ordered two or three packs of these devices and they all worked and were very useful. I've used them on HDMI splitters and they work great. One of the main things I use them for is the HDMI output on my gaming laptops. For some reason they often place the HDMI port on the right side, which gets in the way when using a mouse with a laptop (especially using any laptop). This angled adapter routes the HDMI cable to the back and keeps the cable from being as annoying. It's good to have both 90 and 270 degrees if needed. I would recommend them for HDMI cable management.
