We've got five too! Ages 4-14. I was very glad I knew right where the fire extinguisher was Tuesday and had no trouble getting to it. Even more glad I didn't have to use it! I do think we'll be getting a few more though to have them in other areas of the house that are further from the ones we do have. I figure we should I have one in every area branching from the stove that way I'm not crossing the house for one or having to go upstairs or something. It also seems to boil down to as safe or as dangerous as your crook dealer seems to think is ok as we are finding out. It's unbelievable.
