I don't think the one I received is a full as shown in the picture.  I have mine outside in a similar container, probably even a bit narrower than shown in picture, but is half as full as that one.  I still need to add my batteries but trying to figure out what I can add to make it look a bit fuller.  I did give these 4 stars because it came well packed and looks nice, just not a full 18" around.
