I have been actively involved with many of these SoundDocks, but I decided for this. In my case the machine is on the nightstand and wakes me morgends or helps me fall asleep! And for that, it is wonderful! As space sound absolutely unsuitable, but the price / performance ratio is great! Oh, I can recommend to anyone who wants something simple and functional!
And also very nice: the iPhone 4 is everything: it is loaded and you do not also turn into an airplane mode! No noise or anything like that! Simply a good job!
