Test device was not extensively since the Aux input from the outset was broken. Bluetooth works well so far, but with even casual interruptions. The sound is now not just so, but that falls from the chair for the price that's fine. Lustig just that is spoken in the guidance of hifi speakers. To operate you do not need instructions, pairing with devices working properly. For the beach or kitchen just fine, but if you want something useful, one should spend more already. Accessories is fortunately doing, such as a USB cable and an audio cable for connecting MP3 players etc. Even a bag included, but I do not have it managed that device to get thereinto. Does not fit. Let's hope that I caught a Monday device ... Conclusion: For the price okay, but but nothing more ....
