Great product for ease of use, easy to set up, good with music IF you just use the audio out. The sound is not bad, but not as good as an external DAC. So here is the problem Apple, try to use the optical out to a DAC and yes the sound quality is good, the signal breaks up though!
Bought this to replace the router function of my virgin super hub. Easy to setup through my iMac, took literally a few minutes. Solved the constant wifi drops from the VM Superhub. Overall great little device.
Cons: Bit pricey and also wireless signal not extremely strong for even my 2 Bed Apartment, but enough for me to use in lounge.
I mainly bought this for AirPlay use - it's superb. I can now box away my old CD player and CD's
However, one other feature which I hoped would be better was to use it as a wireless bridge to an existing network. Now if you have an Airport Extreme it works (from what I've read) - but for me with a Draytek (Seems it only really likes the Airport Extreme) router it doesn't.
It's not the end of the world to be honest - I should have read up about it first and as it's primary role is AirPlay I'm very happy with that.
Overall a nice product, same size as the Apple TV 2/3 and the fact it's got a separate mains cable now means it doesn't fall out of the wall like the previous version of the express.
