Unfortunately, you can't manually set a countdown time; you're limited to the aforementioned five options. You can use this as a traditional alarm clock in either 12- or 24-hour mode, however, so it's suitable for nightstand use. The device is powered by a pair of AAA batteries (not included).

My only real complaint is that the numbers are kind of small relative to the overall size of the clock, and there's no backlighting to help you see them in dim lighting. But I have one of these, and it's already proven a great addition to the kitchen. Love the look, the simplicity and the price.
