G.T.
I love my electric warmer, it does candles and/or tarts or oils. You just have to dump it when it's hot so all the wax comes out and wipe it out with a paper towel.
Just a note of caution on the ones with the tea light burners, I had one explode on me once after it got old. Well it didnt really explode, it cracked and then there was a mess.
