Query: awesome...for three days.

i just got this a few days ago. i LOVED the ocean sound. it was perfect. unobtrusive, incredibly relaxing.three days later, only the rainforest sound works, and then only if i scotch tape the button down, and have the machine at a certain angle, almost upside down.lesson: spend the money on a non-disposable sound machine. darn it.
