So I loved this tree! But, after 4 weeks of only being plugged in 3 hours a day, the entire bottom portion blacked out. I bought another strand of lights to wrap around it and called wayfair. 

I was worried I would have to send the whole tree in. They are sending me part c, the only part that is missing. And they dont even need my defective part c back.

I have bought a lot from this company and never complained, but I love their policy and will continue to be a customer.
