Query: Wonderful Sound Machine, Wake up to the ocean waves.

This Sound Machine/Alarm clock works great. I love how it projects the clock onto the ceiling. No more need to look over to see what time it is. One thing I did notice was that it is easy to change the time on accident. Overall though it is a great tool if you want something other then a buzzer or radio to wake up too. I even enjoy listening to the sounds before bed.
