The speaker itself is well made and looks chic. Despite its small size, a decent sound comes out even at higher volumes. Our apartment is 112qm large and you can hear well if you "turning up" him in every room. The connection to the WLAN (Fritz box 7390) worked perfectly. Likewise, install the app on my Samsung Note 3 Neo with Android 4.4. The self is in need of improvement. Still too little content is offered (eg Tune In missing). Every now and then the error message that playing with the device is not possible. Then just close the app and restart. Then it'll work. Too bad that you do own music only needs to load on the mobile phone in order to be able to then play with the app. It would be better to let such as music files to stream from a NAS drive via WLAN.
