I have purchased two sets of these candles so far, and going to order at least one more set of four! They work perfectly and look awesome in my windows; leaving them for all year long! No cord to mess with, and the timer works so that you just put them in the window and forget about them, until they need a new battery! The batteries lasted at least 3 or 4 months...and they were just cheap batteries..........very happy with the bronze color and soft warm glow!!
