What has surprised me is how effective the voice recognition is. Even with my poor voice, it seems to understand me most times. When not in use we turn it off at the mains to prevent it picking up unintentional conversations.
When it arrived it was much smaller than I expected. At first I wondered if they had only sent the PSU. At a guess I reckon it is about 10cm across. Sound quality is much better than expected. It is very good.
You can say things like, "play BBC Radio 4" or "play a 1930s mix".
I am impressed. It is much better than I expected. My wife enjoys it even more!
