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.
