It works and is pretty BUT a regular plate won't fit INSIDE the dome because the dome is the dimension of the plate itself.  It would rate 5 stars if the dome was 1/2" wider to accommodate a plate the cake sits on.  As it is, you need to hunt for something to put the cake on.  If it's a bakery cake, you're ok because those come on a cake board.  If you are baking your own cake or wanting to put cupcakes on a PLATE, good luck..... Salad plates are too small and there's NO WAY I'm buying cake boards or making them.  I'm giving this one away as a gift because I don't want to pay to return it.

Don't think you'll just set the dome on the plate that is the same diameter as the dome itself.  Just don't.  You'll end up frustrated with a chipped dome, plate or both.   Or worse yet, the plate can become slightly skewed and lodge inside the dome.
