I have to say I was worried this was too narrow because the slim tree I originally ordered was 41" in diameter compared to this one at 37" (which also got great reviews) - it was cancelled when they discovered they had no more in stock.  However, this tree turns out to be the perfect size.  I worked hard getting the branches fluffed out to my satisfaction, and it looks awesome...although I still have a a little tweaking to do as some of the lights are not evenly distributed.  It will be absolutely beautiful though once that's accomplished.  And the LIGHTS!! Wow!  Just awesome too and love the different light options - LED is so bright and much better.  I kept the tree up for a couple of days just admiring it, since it is after Christmas, but I wanted to be sure everything was working ok - because you only have so long to return it if not.  I can't wait to put it up again next year and decorate it!  Very please!
