I was very disappointed in this tree.  it is not cheap.  I put it all together, took it a while and then realized this tree did not come with an option for flashing lights.  a 400 tree on sale for 200 should twinkle.  I packed it up and it is going back and I do not feel the customer service was helpful.  Anyways went to Home Depot and paid 89 dollars more, but got a 7 1/2 foot tree that has 10 different light functions.  I am now actually glad this tree did not work out because I love my tree from Home Depot.  do not recommend this tree.
