I love this whirligig! It is for my husband's birthday next week, so we haven't set it up outside yet. I did get it out and spin it inside the house, and it is very smooth and so much fun to watch. I wondered how big it would be, and would say that it is about the size of a large dinner plate or a hubcap (as comparsons go!). I cannot wait to see the center light up at night when we do get it set up!
