Eventually stopped working
I bought this product because my neighbor plays their tv extremely loud and it would wake me every night. This noise maker did the trick.  It helped me sleep through the night without hearing my neighbor's loud tv but after 4 months it began cutting in and out and eventually stopped working.  It was my best friend. I will order another and let you know if it does the same thing again.  I can't sleep without it now.
