Review on JTECH-18GAE 4K@60Hz HDMI Embedder with Optical and 3.5mm Audio Inputs, Supporting HDR, CEC, and HDCP2.2/1.4 at 18Gbps by Brandon Barrett

I really like this company's product line. So much so that I bought 2 of these units compared to what another company was offering even though they cost more. size exceeds. Heck, this device is surprisingly compact. Another bonus is that all the boxes I've bought from them (mostly HDMI splitters) run on 5V 1A, making it easy to connect to USB power with the right cable.
