I had the previous model Airport Express which was of limited quality. Far're very easy to configure, good signal range and latest generation Wi-Fi (a / c). I use it in an environment very "cosmopolitan" (PC, Mac, Android, iPad and various stereo subsets) have I encountered no problems despite certain "exotic" to some of my device. Very aesthetic and discreet, its shape is suitable for placement over a cabinet for example.
I highly recommend this product that I use for several weeks now
