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.

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.

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

Long, Thin Cable Easy to Hide
The first one didn't work but the service and response was quick and the second cable worked great. The cable is very thin and was easy to hide between the carpet and baseboards. It also didn't take up much room in the cord hider.

HDMI fiber optic cables at Amazon are bad quality
3 months in and it stopped working. Since day one it had issues but would work until it went dead. Seems like all these fiber optic hdmi cables sold at Amazon last a few months and by the time you want to report the issue to get a re-lacement or refund you are out of luck ; so leaving a negative well deserved review is the only option.

AVアンプと4Kプロジェクター間に使用しています。 プロジェクターはGoogleTVを積んでおりeARCで音声 を伝送できます。以前使用していたHDMI2.0対応の 光HDMIケーブルではARCすらリンクしませんでしたが こちらに換えeARCで音声を再生できました。 もちろん4KHDR60Pも問題なく伝送できています。

An jeden der schonmal ein normales HDMI 2.1 Kabel mit 9 Meter+ gekauft hat und dann nur Probleme hatte --> das hier ist ein Gamechanger! Keinerlei Probleme selbst bei 4k 144Hz und HDR. Top
