-Spectacular fit and finish
-Great sound (compared to other AirPlay speaker systems)
-Easy set up
-Relatively heavy (may limit placement)
-Cannot use special characters for WiFi password. (! are OK)
If you've ever setup a non-Apple wireless router before, then setup will be a breeze. If not, just follow the simple included instructions. Will not work with WiFi passwords which have #,$,% etc. Frustrating that this wasn't mentioned anywhere in the manuals (a quick web search led me to their support page).
After setup, it has performed flawlessly with my computer and various iOS devices. Sounds great, except maybe to serious audiophiles.
Very happy with purchase. Simplified previous setup, which was a pair of speakers connected to an old AirPort Express. Would buy again if I was looking for AirPlay enabled speakers.
