Well done Google. Product is well built -- even though is plastic -- but it pairs nice with other audio gear. I left mine alongside with my guitar and other audio stuff, since they're at another room. So whenever I want to listen to Google Music -- Bang -- it is quite easy to launch it with my Galaxy phone. Installation was quite easy as well. My recommendation is planning in advance. This was an important piece for my gear collection.

We are music-lovin' fools and have been trying to create a cheep sonos for years. This is the ticket. Anything you own with an auxiliary input is in sync.

Optical output it's a very good and the connection with the Spotify is simple and fast.

So simple and does exactly what it describes. Very easy setup. (I did have to call my A/V receiver manufacturer 4 help W/their setup) Once connected & downloaded Google Cast App device went right to work. All my music Apps working seamlessly! Thanks Google.

it is a super fast way to add whole home audio to existing speakers and audio systems. The quality is decent enough that you can tell a difference depending upon the quality of your speakers.
