Query: Cheap piece of junk

My 7 year-old daughter received this from her grandmother for Christmas. At first we thought "grandma actually bought something cool and educational"...but no...it's a piece of junk. As others have stated, it's flimsy and cheap-looking, and the star patterns are barely visible on the wall. You would have to be in a room the size of a doghouse for this sphere to accurately show any constellations. I guarantee you will regret buying this product.
