the only problem with the high wattage warmers is that some of them get the wax over 180 degrees and all of your FO burns out. I had this happen to me - put my candle on a warmer and after an few times it stopped smelling, got out my handy dandy thermometer and it was getting somewhere around 183, enough to burn off your FO. So I've warned all of my customers that were buying the jar candles and using the candle warmers. Right now, I am using a coffee warmer, if it doesnt get too hot to drink, it isn't gonna burn off your FO.
