Once unpackaged and powered the set-up wizard automatically kicks in. I followed the steps, mostly without reference to the manual and had one minor hiccup: The radio could not connect to my wireless router unless I simultaneously asked the router to search for new devices. This point was not covered in the radio's manual, but once I'd sussed what the problem was the connection worked fine.
I then searched the stations out that I wanted by inputting a keyword into the radio, and stored them in its 10 station preset list.
Initially the time was displayed for another zone, even though I'd correctly set the zone to Greenwich. I left the radio like this overnight and found it had corrected itself the next morning.
Sound quality is what you would expect from a single cone speaker in a plastic housing. Its fine for casual listening, hi-fi it is not.
In summary its priced right at £90, easy enough to set up and has worked flawlessly since. I would add I've not tried to stream from my PC's collection of stored music.
UPDATE. After 2 weeks the unit failed when mains powered. It would not power up at all. On batteries it worked fine. Amazon's exchange was smooth and well communicated. The second unit is now in service. If I don't update then ,it means that its lasted the distance. I've downrated from 5 to 3 starts as a result of the failure of the first unit.
