The shape of the tree is beautiful!  However, one of the sections would not light up and my husband and I couldn't find the source of the problem.  If one light is faulty it seems the entire string in that section will not light up.  It was extremely frustrating trying to source the problem.  We never did!  We ended up putting a separate string of lights just on that one section (lights that will not go out if just one bulb is faulty).  We had the tree erected when we noticed the problem and didn't want to take the entire tree apart to return.   I'm guessing it was probably cheaper for the manufacturer to fill the tree with this type of light string.
