This tree was fine last year—it requires quite a bit of fluffing, but wasn’t too difficult.  It has a nice shape and the color changing features were nice.  We just took it out of storage and half the lights no longer work.  We pulled up the manual and surprise! the instructions don’t match.  There is no discernible way to check or replace the fuses.  And the warranty  Good luck.  Buyer beware—anything beyond the first year requires that the buyer pay shipping to and from the factory.  Add to that the fact that we would have had to have gotten it out of storage in August if we wanted to get it back in time for Christmas.  I would expect to get more than one year out of a 400 Christmas tree!
