Too loud; actually disturbs my sleep!
I agree with Jess, who found this sound conditioner as extremely loud.  I didn't get any instructions with my order--just the item in a box.  However, I put the machine on my dresser, which is clear across the room from my bed.  Even adjusting the sound so it is on the lowest possible level, it is very distracting and not helpful whatsoever in my sleep.  I will be returning it.  I am frantic to find a really great sound conditioner, something that puts me to sleep the way the ocean sound does.  I'll keep looking.
