I have ordered many illumination warmers and they have never smoked. I did have tons of issues with the Tuscan Brown Warmers, they would absorb wax and leak through. I had the same problem with the plug in warmer in the same style. They say this problem is resolved. Sorry for rambling. If I were you I would call customer service, they have been wonderful to work with when I have had problems. Also thought I would let you all know one of my snowman warmer had his arms painted on backwards, so it is always best to check the warmer before it goes out to the customer. :
