We purchased this a few months ago and took our time applying two coats of waterproofing to the wood before assembling it.  My husband and I put it together relatively painlessly.  It took the estimated number of hours but would have been less if I hadn't missed a few Tnut installs along the way!  They were in the instructions so that's completely on me.  If anything were to happen to this one, we would absolutely buy the same exact one to replace it.  Also, I am 5'3" and can stand up straight in the center of the fort area so there is plenty of room for the kiddos!
