Edit, still not resolved, had no lights on the trees because Wayfair is taking way too long to resolve the problem. Sent partial items that were missing but still enable to use the tree because still waiting on additional parts. As of right now these trees are a waste of money. 

Love them! Had a problem with the transformers not being included but Wayfair quickly responded and got them to me. Very happy with the product and with how Wayfair responded to my concern
