I bought the equipment for the holidays, and so far it has completely met my expectations.
It helps me a +/- list always the fastest, so now is a)
+ Very good battery life (Did the device a week, every day several hours used, without having to load it)
+ Compact and handy (Does not much space the small speakers. Fits in any pocket without any problems even in)
+ Bass, unfolded (The bass is not to be compared with a subwoofer, but top for the small device)
+ Volume (Connected to my MP3 player, I have the device rarely turned to full volume)
+ Separate volume control (normal control dial)
+ Delivery (pocket and cables, everything here that you need)
+ Connected to other equipment possible (not yet used)
+ Warning lights during operation and charging
- No easily replaceable battery (is to load a USB charger or PC required)
+/- Whether the cables are made to last, or arise below the jack of the device cable breaks with frequent use remains to be seen.
+/- To pull down the appliance you must first times the rotation have to get out, but is not a problem.
The device is well worth its 20 definitely.
