What are all the attachments and when do we use them? I am looking to understand all the different things I can do with wax/budder/shatter. Currently I have the cartridges that I can pack, (Load as You go?)...but I see all these other "cartridges with different names like cartomizer, clearomizer, atomizer...etc. How do I get my shatter/was/budder into these long clear cartridge? are these only for oil? can my stuff be turned to oil? I am so confused... can someone help me out so I stop sounding like an idiot?
