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.
Review: EXCELLENT PRODUCT: JUST BE SURE TO CONNECT THE RIGHT WAY! - Buying a 3.3 foot fiber optic HDMI cable may seem like overkill, since fiber optic is only “necessary” for much longer cable runs. But the advantage of even a short run of fiber optic HDMI cable is that, unlike copper, it’s totally immune to radio frequency interference (RFI), which can cause signal degradation, data loss, and — if the RFI is bad enough — malfunctions in your surround sound system. This particular cable is very well made and works flawlessly with my Roku Ultra, Denon AVR, and LG TV — all hooked up with ethernet connections in preference to wifi. Note that fiber optic HDMI cables are uni-directional, with one end labeled “Source” and the other end “Display.” If you have a streaming device and an AVR, the “Source” end of the cable plugs into your streaming device and the “Display” end plugs in to one of the HDMI ports on your AVR. You will need a second HDMI cable to run from your HDMI OUT port on your AVR (“Source”) to an. HDMI port on your TV (“Display”). Unlike copper HDMI cables, which are bi-directional, if you plug fiber optic cables in the wrong way they won’t work. For me, this was a great buy, with excellent build quality and easy installation. Last but not least, measure (twice) BEFORE you buy, and if in any doubt go for a longer cable (e.g. 6 feet). Stretching fiber optic cable is a very bad idea - both ends need to fit snuggly with no tension on the cable.

Does the job very well, and much thinner than the usual HDMI wire. Just make sure to avoid sharp angles.
