The only thing it is missing is some type of rack with a screen so thst yoy csn place plant material inside without it sitting in the water if you want to make essential oils. The pipes could also be longer so you can keep the final product as far away from the heat source as possible and the rubber gasket doesn't fit all that well around the lid and creats problems when yoy try to close it. Yoy may want to upgrade it for something better and make sure you have a very strong fan in a window with a second fan directing air flow too it, just incase yoy use the gasket that comes with it.
