Bluetooth loudspeaker in hand grenades design with suspension, which also came to bear even on a swing hanging on the tree. For the not so demanding listener, therefore am very satisfied about the sound performance. Coupled quickly and easily with smartphones, tablets, etc. The range is also perfectly adequate. Especially great and uncomplicated is the hands-free function and the battery power (> 8 hrs.) Only criticism: The speaker diaphragm could be a little more protected. Has not yet been crushed by children's hands ;-)
