I have the old Chromecast that only supports 2.5ghz. It doesn't run 1080p smoothly as it's get choppy at times and takes a while before my phone finds the Chromecast on the wifi so I can control the volume or to pause. There is no way to scroll forward on content that isn't on YoutTube. Sure Chromecast is cheap, but we weren't looking for cheap and the frustration isn't just worth it.
