There is a design flaw in the one that I received.  One of the metal pieces with the decorative blue pieces is right above  the lower candle.  I lit it up last night for the first time and had a tealight in each holder.  I also lit other candles that I have.  All of a sudden, I could smell something burning so I start going around the house to see where the smell was coming from.  The blue plastic piece had fallen off the metal and right into the tealight! I should have known better and returned it after seeing how close that metal piece was to the candle holder.  I plan to contact Wayfair and see what they will do about it.
