this is a really good speaker.
i didnt have much space in my room, so i needed something small, and this was great. the design is very cool as well, t stands out from the usual ipod speaker/dock. i dont see why you would need to buy a more expensive speaker than this, because this one is very compact, very good quality sound, and looks very nice.
it is really cheap as well! because of the price, i thought that maybe the sound wouldnt be that good, but it is excellent quality. the volume goes louder than needed for any room.
you can charge it with the power adaptor (not included) or you can use batteries. when you switch the speakers on, it also charges your ipod.
the only thing i would say is that if you are looking for a more complex speaker, then dont buy this. all it has is volume control and an on/off switch.
