Query: Need a basic alarm clock? This is it.

I agree with another reviewer's suggestion to read Weatherman's review. It is a complete description of this clock and how it works. Simple to set time and alarm. The time screen glows an easily readable, but not harsh, blue when you push the snooze bar in the dark. It only glows while you are pushing the bar - a battery saver. I always read the Amazon reviews, no matter what I am buying. Based on the reviews for many of these inexpensive clocks, this is the one I picked. I have been using it about a week and the clock and the alarm work well and the price was very reasonable. Good purchase.
