Fantastic device to sleep, concentrate, or annoy people.
Great little machine, I find it really relaxing to fall asleep to the sound of a thunderstorm. I also use this to not only fall sleep but drown out other noise around me to concentrate.<br /><br />Some of the sounds are relaxing while others are extremely annoying to some people so if you want to be left as lone select the appropriate sound to play. The ticking clock sound is extremely effective for this--hint hint.
