I purchased this tree and immediately took it out of the box only to have the top tier of lights not working. I was so disappointed because the tree itself was really nice looking. Well, I ended up doing an exchange and the replacement tree I received had the middle and top tier not working!! At that point I was really frustrated. I ended up returning the tree for a refund... still waiting for my refund as it's only been 1 business day so far. It seems based on the great reviews I had some bad luck.
