This is being returned! Immediately! As soon as I put batteries in it, they started to heat up and the lights would not activate. The batteries got so hot I was frightened and of course took them out immediately. AND YES I double triple checked that the batteries were facing the right direction. Not worth a house fire! Also gave it one star because Zero stars is NOT an option.
Output:
negative
