Title: Two of Three received devices do not alarm nor provide light!
Review: I ordered three of these units after reading the reviews and understanding that the alarm is not very loud.One of the units was to replace a similar device which did not include an alarm and the other twounits were additional units for additional locations. I plugged all three units into live AC receptacles andlet them charge for a week. The dim green 'power on' indicator was lighted on all three units. Today, I decided is was time to see if they worked.Only ONE OF THE THREE units alarmed and provided light from the three LEDs. The OTHER TWO units did not work at all!I purchased them from one of the sellers here on amazon.com. Today, I called the seller and they promised to ship out two replacement units.They do not require that I send the defective units back. I like the fact that the AC Power prongs do not fold. I have had problems withfolding prongs arcing and burning the metal which they contact on the mating Printed Circuit Board.
