Wireless HDMI Transmitter and Receiver Set - World's Smallest Class - LLANO

I purchased this a few months ago, but it's no longer needed as I bought a TV.
I've used it for about a month, and there are no issues with its operation. The instruction manual is also included.
Please understand that this is a used item before purchasing.
