I wanted some inexpensive battery powered candles to go on the corners of my bathtub since I did not want wax on my candelabras. A year later one of them, I have to take the battery in and out to turn it on. The switch no longer works. Looks like it may have rusted on the inside. However, they never get wet. The only thing I can think of is that since it is in our bathroom, when we take showers (even though we always turn on the exhaust fan) moisture may have gotten in the candle and caused the rust but only to one of them. Other than that, they are great!
