Review on Infrared Remote Extender Cable - IR Extender with 1 Emitters 1 Receiver (20FT) for Cable Box Hidden IR Repeater System by Tina Harris

Works great. I tucked the soundbar under the TV and didn't have enough room to turn the TV on with the remote. I have a LG C9 OLED. The remote control uses Bluetooth for all TV functions, except for turning it on and off, which uses an IR blaster. Needless to say, this device is perfect. This didn't work when I was using the USB port on the back of the TV, but it works fine when plugged into an outlet. It doesn't even have to be clearly visible on the remote control. I pointed the repeater down on the back of the TV - you can't see it at all and it still works fine.
