Query: Yup, it's an alarm clock alright

Hmmm...what to say? I expect two things from an alarm clock: 1) it keeps relatively accurate time, and 2) it wakes me up when I want it to (even if I really don't want to wake up then). This does both quite well, plus the dial is backlit so it can be seen in the dark. Whaddya know - a product that consistently works as designed!
