No more baby cries
I bought this white noise about a month ago and I love it.  I purchased it to drown the baby cries of my neighbor's baby that lives below me.  Without fail the baby cries at 4a and tends to wake me up.  At full charge, the box last me about 10 days and I tend to get about 7 hrs sleep. It stays on until I shut it off in the morning.  The volume is ok, I flip it upside down as the speaker is underneath to get a louder sound.  I am happy with it.
