Mediocre
The cartridge roller doesn’t work. After leaving the wax cartridge in the warmer for over an hour, the wax would still not roll out freely, and the cartridge burnt my hand while holding it firmly enough to try to squeeze the wax onto the roller. The first cartridge had a small piece of foil stuck on the under side of the roller and when that  was removed it moved freely. This second cartridge doesn’t appear to have anything stuck it in and won’t roll even when using your fingers to try to force it to move.<br /><br />The warmer is fine, the cartridges could use quality improvement.
