Review (5/5): Working great for over 9 years.
I have had one for about 9 years. It works great. It doesn't take long to heat. I always heat on low for just enough time to heat what I need. When it starts to soften I stir it and use it. It still works, but I accidentally left the lid off the can while traveling and the sun melted the wax and made a big mess all over the outside of the warmer. It's cheaper to buy a new one than buy chemicals and clean it.
