More than I need. All they are is dust collectors and if they hadn't been given to me by close family members, I would toss them all. In fact, if I ever move out of this apartment, that's exactly what I'm going to do.
There're still 3 or 4 left on the hearth. I don't get along well with breakable objects. Every encounter we have inevitably ends in a "break up" (get out the vacuum).
