i dont like the size of the holes on the screens. screens are very easy to use though, just plop them on and they are ready. they dont last forever though and you do have to replace them after so long so personally i see it just as good to use foil.
you get to choose how big are the holes and where they are placed for the perfect smoke. you can rotate the foil depending how you put it on, personally i rotate mine so the same thing a screen does in foil form
. cleanup is a breeze with foil, i just use it to scoop out all the tobacco so no need to take it out with tongs or your fingers getting them dirty.
