This is one of the most durable and quality fill your own vaporizers. It works with all concentrate, wax, shatter, rosin. Not recommended for hash though because it can burn out your atomizer. It comes with a spill proof lid on top of your atomizer and a silicone lined dual container at the bottom of the unit. The heating element on this Evolve XL is twice as big as the Evolve plus. It has a quad quartz coil instead of a dual quartz coil. Also it comes with a magnet top not a screw on top like the evolve plus. It also has a micro USB port on the side for charging.
