This was really easy to put together and we had no trouble with the lights as we have with some other trees.  It does take a fair amount of time to fluff out the branches but this is necessarily to make it look good.  And it is a tad tall for our ceiling.  We could not put a topper on it.  But it is the best looking tree by far that we've ever had!

Pros: Easy to assemble, looks wonderful
Cons: None
