I bought this lighted sign to put in my front window. It was very simple to set up. I just put 2 AA batteries in, turned it on "Timer" mode, and for 4 hours my window was lit up. For a battery operated sign, the lights are amazingly bright. I also put a candle on each side of the sign, and now my front living room window looks "Joyous"! If you want to extend the time of the timer mode, just turn it off then on to timer again, & you get another 4 hours. This sign is not only easy to setup & use, but is beautiful.
