I have a Nantucket Blue Spruce tree I purchased in 2015. (Order 711492.) There was a dead strand of lights in the middle section from the first year. They told me to replace the master bulb. That did not work. This year the connectors between the sections would not work. Only the bottom section will light up. I called and cannot even purchase replacement parts for the pole connectors. For the price of the trees, the quality of the product should last longer. It is disappointing that they basically said there was nothing I could do other than run an extension cord through the tree and buy a new strand of lights. The whole purpose of purchasing a higher end tree was to eliminate the hassle of having to put on the lights every year.
