Monica's Review:
The unique power feature of the clocks has made them a hit at our events. Due to their higher cost, we made them a "big prize" that only some people randmonly earned. Anyone could walk away with a gift for stopping by but those who took the time to learn about home fire sprinklers (thus the water connection to the water powered clocks) were given a scratch card which either had "clock" or "prize" under then scratch-off sticker. Some people came back to learn more to get another shot at winning a clock.
