This is my first projection clock, and I'm quite happy with it. The numbers are big and clear on the ceiling. The alarm feature is easy to use. The alarm could be a little louder - fortunately I wake up easily to a soft alarm, otherwise I'm not sure this one would wake me. I have had trouble with resetting the clock; it seems to have a little difficulty locating the atomic clock signal. Once it's located, though, it runs flawlessly (until the electricity goes out again!)
