We bought our Balsam Hill Pre Lit Tree a little over 3 years ago. We get the tree out to put it up for Christmas this year and none of the lights in the top section work. My husband did a little investigating to figure out which bulb needed to be replaced, there were several bulbs not working. He took the strand off the top of the tree. After working on it for over 3 hours, we've decided to just buy another strand of lights to add to the $700 tree! Since we bought it over 3 years ago, it's not under warranty! It's poorly wired. Some of the bulbs are also very hot. Very disappointed!
