Re: heba diffuser
very simple, there are 2 parts usually, the clear rubber connected to the white plastic piece slides onto the end of your stem, you want to submerge the entire white part.
you can use 2 at once the big and small, or just one depending.
sometimes its a little tight so you might have to force it.
