It feels like it will last, it looks great and the kids love it, so we are very pleased. 

I built it by myself in about 18 hours, with maybe 20 minutes total of help from my wife when I needed a hand holding things up wile attaching different parts. It wasn't as bad as I expected.

One minor point: the screws and other hardware are not fantastic quality. Some of the bolts would not thread properly onto the screws and one screw sheared in half while I was twisting it into a bolt (by hand, not with a drill). This did not create any major issues for us because the set came with some extra hardware, but we almost ran out of extras, so I can imagine that some people might have issues. Still five stars though!
