Set up wasn't straight forward. 1) The Chromecast required an immediate firmware update. However because the wifi signal wasn't super strong in the room with the SmartTV, the update wouldn't load so I had to move the Chromecast to another TV closer to the router. 2) Then (after moving the Chromecast back to original TV), I did the system setup, and it changed the default feed from cable to Chromecast. I went to Best Buy for advise and was told "that happens" but it shouldn't impact your use of cable. But it did and I couldn't revert back to the original set up. 3) Also, one reason for my getting the Chromecast was to cast from my mobile phone and tablet to my TV. After installing, I learned that Samsung builds casting into their TV for use with Samsung phones. Since I had a Samsung SmartTV and a Samsung phone, I realized that all the hassle wasn't worth it. So...after many hours of making everything work, I ended up returning the Chromecast.
