The Sony Dream Machine radio/alarm clock has been my trusty morning companion for several years now. This little box with a green display is a wonderful alarm clock. This little thing is bullet proof, I have dropped it, left it in sub zero temperatures, taken it camping and everything it is still working perfect and it keeps perfect time, and wakes me up every morning. It's sound quality is what you'd expect from an alarmclock, it's not bad, but not wonderful as a home theatre system might be. It has a range of frequency enough to get all the radio stations I know of. The battery life is not applicable although it does have a place to put a D cell battery to keep time when and if the power goes out, which is nice. It picks up signals very well, no need to stand on your head to get a good quality signal. This is an A-1 product and I recommend them to everyone.
