After 2 Christmases most of the lights no longer work.  We store it in a large closet and don't have to take it apart.  We just carry it upstairs and cover it with plastic so the tree has been well taken care of.  I bought it because I hate putting lights on real trees but I find I spend even more time trying to get the lights on this to work and/or putting more lights on it. I am very unhappy.
