Review on HDMI to AV Adapter: Benfei HDMI to RCA CVBs - PAL/NTSC Compatible for Fire TV, Roku, Apple TV, PC, Xbox, HDTV, DVD by Rich Shankar

So far I've tried this device with NVidia Shield Android Tablet HDMI out and 2nd Gen Chromecast. In both cases it worked very well with both the AV inputs of a modern 4K TV and an old NTSC TV. At first I had a few questions. Android Table didn't recognize the HDMI output until I restarted the tablet. The first time I connected the Chromecast, the TV only showed noise, but the second time it worked. I don't know what the problem was, but now everything works fine. The case is made of durable plastic and all ports are physically solid.
