I think the biggest draw for me was the auto timer. No one wants to turn their lights off/on all the time and having to go out in the cold late at night is a buzzkill so being able to have them cycle for 6 hours and shut off saving battery life. AMAZING!! No more extension cords run all over, just a clean set of great lights. Make sure you have some D sized batteries on hand since this takes 3 of them and read through the included manual a bit to familiarize yourself with the different buttons and modes.
Overall, great light set - easy to use, beautiful to look at, and an excellent price.
