ROOFULLBi-Directional Digital Coaxial to/from Optical Toslink SPDIF Audio Converter/Adapter/Repeater

Works as it should.

Worked for 6 mo. then developed some clicking. I contacted RFTECH (the seller) who quickly helped with troubleshooting. Ultimately replaced the unit without any hassle. Thanks RFTECH.

I could not get it to install on my tv. I tried several different ways to install using different cables. Only got static or no sound. Seller offered assistance but I opted to try a different product.

I got this to serve TV sound out on an old TV which had no HDMI ARC and no optical audio. Now, the TV sound goes to my Roku Streambar for any input which is not the Roku. I haven't noticed any audio delay due to conversion, either. Setup was essentially plug and play.I will update if this device fails anytime soon.

Product effectively bridges my 12+ year old tv with new soundbar. Included cables make connectivity and setup super easy. I recommend using your tv to power the device via usb so that the device is not constantly powered on while not in use, as the manufacturer warns to not leave device powered on when not in use. Take time to study what connections you’re trying to make to insure this is the actual device that provides desired connection chain. My older tv did not have a digital optical port onboard, but rather a digital out jack. I prefer 5.1 surround sound audio quality to get the full audio experience while watching shows and movies mixed in more than left and right channel audio spectrum. This device allows addition of greater clarity and detail to the audio perception as was intended. This device allows me to continue using older equipment (tv) with newer equipment (5.1 surround sound system) for a fraction of the cost! In other words, my older tv did tv is now compatible with my new surround sound system without costing an arm and a leg!

***Update again. Same recurring problem with the new unit. This works but not in the long term. I am going to try another brand. You get what you pay for. I'll spend more now and maybe have better luck.**Update to previously negative review. This company stands behind their product. Seller Customer service was very helpful and responsive. We got the unit working again. It is important to use the power supply that came with the unit and not another power supply, which turned out to be one of the problems I was having. The power supply of the original purchase was defective and this company sent a new unit even though out of the return window. I am very happy again with the quality of sound this unit produces. I highly recommend.Very easy to install and sound quality was excellent after I hooked smart tv up to stereo receiver. I have been using it for approximately 27 days, on a daily basis. Turned it on this AM and it worked just fine for about 1 hour and then sound level dropped so low I could barely hear anything. Turned up volume to max on receiver and the sound was very fuzzy and full of static. Basically not tolerable. Even though I had no problems for almost a month, and the setup had not been touched since the original install, I tried to tinker with the volume and audio controls on the TV. Nothing I did corrected the problem. Finally I turned everything off for 20 minutes and re-started. At that point the excellent sound quality I had before returned. Everything crystal clear and sharp again. This should not happen. I have started a return. I need something that works without constant tinkering for much longer than the time I got with this device. I don't recommend.

Not outputting what it advertised. Little disappointed.

nice little unit. there's a switch that select what type of audio input it's receiving (coax {aka rca composite yellow connector} or toslink. i assume that it outputs to both coax and toslink ports (i'm converting coax to toslink and it worked perfectly). it needs AC power because of the optical connections.
