Review: Great product - Does the job very well, and much thinner than the usual HDMI wire. Just make sure to avoid sharp angles.
Review: It's good but don't bend it - It worked perfectly until unfortunately the door was closed on it which bent it just enough to break it. Be very careful not to bend it.
