I got this speaker and hub free with a Samsung TV - and being moderately geeky was really looking forward to getting it set up and using it. Set up was easy - wifi to the hub, Ethernet to my Virgin Router. However, then it becomes unusable - I have an iphone running IOS7 and the app can't find any music. I also use Spotify, and like the previous reviewer - also found that it will not cast to the speaker it just plays on my phone. I have music stored on a NAS drive, which the app cannot find. I tried to use the PC application - which won't run on Windows at all that I can tell although I have studiously downloaded the Windows version twice and updated my PC with all the latest updates. The only thing I can make this speaker do is play radio - and I already had a radio.
I'm glad I did not pay for this, it is just pretty junk.
