No Continuous Sound
I was happy to get my white noise machine but disappointed when I went to bed at night to see that the "Infinity" button for continuous white noise does not work!  This will not stay on all night.  I was waking every few hours to turn it back on and that's pretty bad for sleeping.  Also because of the term "portable" I was under the impression this could be charged and did not have to be plugged in somewhere when it was fully charged.  That is not the case.  It must stay plugged in at all times and does not charge.  I am returning to Amazon.
