Clunky and jittery. Setting up devices is horrible. It is hard to tell if you are setting up a device, a user, an account or anything. When you finally get to the phase of casting to the device, it can pause, buffer or simply never play. Instead of using Chromcast I generally will load up my laptop and connect to an HDMI port on my TV. I don't usually feel like playing the "will this or won't this play on Chromecast" game. Playing Google's YouTube..easy. Imagine that! Make it work.
