Have the unit ordered despite mediocre reviews, to form my own opinion - and what can I say, it was the right decision! The device meets my expectations. It can be with music "feed" via USB, SD, AUX-in, Bluetooth, MP3 and / or CD. Just Bluetooth comes in super parties on, everyone can "shoot", "his" favorite Shit in seconds into the unit and all listen with - works fine and makes for fun and humor. And the sound you can in this way also additional help on the "jumps" in which you simply his "favorite Shit" rich bass mitgibt via mobile phone music player app that sounds like this, as it is likely that many expect. The included remote control is nice, you can for example conveniently controlled with illness from the bed everything: radio stations (can be stored), CD track, volume, light and so on! Speaking of "light" - something different, this LED effect (controlled) I'll be happy, also has not any device. For me, as a result, all-inclusive package, even if it has only preprogrammed sound / sound adjustments (differences between jazz, classical, flat, pop, rock you could tell) - in short, I highly recommend it and would buy it again, for barbecues simply indispensable !!!
