Input:
I did not get to use the HoMedics much before it was totally non-functional.  Neither the sound machine nor the clock work with new batteries, after only 10 or so uses.  Plugging in the AC Adapter does not help.
I looked at the warranty, since I bought the unit only a few months ago.  I am supposed to mail the unit postage paid, along with a certified check or money order for five dollars.  HoMedics has successfully made the warranty almost useless for a twenty dollar item.
