I could not be more pleased...
Its working fine with iOS 7, its on a charger, Im using an iPhone 5s, and its masking my neighbors annoying heat pump. Im using white noise over a Bluetooth speaker between me and the heat pump and its steady rather than oscillating. The only problem, and it probably wont bother you, is that it keeps making me think about the TV in "Poltergeist". If I should suddenly hear a disembodied voice saying "Theyre baaaack!" Ill not be very surprised.
