Really like the timer feature & the fact that the light is warm rather then cold/blue white.  I had been using candles that turned on when the sun went down but this was unreliable based on what direction the candle was facing in the house.  They also only lasted 2 seasons.  While I can't speak to the longevity of these candles yet, I am very satisfied with the way they look in my 19th century house - warm and perfect for the season.  Would definitely recommend.
