works pretty good with smash. works really good if you take out the regulator. not to hard to squeez. it could be a lil softer plastic. nib wears out kinda fast IMO. all in all pretty good.
its a good little mop. extremely hard to squeez. works best if you take out the plastic regulator. im running smashin gold and smash red threw it. do not buy this if you want drips, this wont do it.
