Hi. I hope I am posting in the right place. I have the nuova simonelli oscar. It has a four hole steaming tip.Its a prodigious steamer which in the right hands is probably a good thing, but its more than I can manage at the moment. Does anyone know if the tip is interchangeable with other makes ie for a two hole? I have been told that there are only three and four holes tips for the Oscar. In the meantime, the old toothpic in two holes brings it down to a much more manageable beast. On the other hand, if anyone has some tips of a different kind about how to use the four hole tip, that would be appreciated too. Cheers.
