I have had this since last summer and it has been great. Assembly took several hours, but most of it could be done with one person. I took it an hour or two at a time at night over the space of about a week, and only needed help with a couple items. I had all the parts and hardware I needed, with exact counts up until the final steps, where I found spare parts. Everything is well built, and mostly modular. It looks like I could rearrange the panels on the tower and slide and ladder placement without a problem. One small note, the red climbing holds (or rocks) have faded, one in direct sunlight, one on the shady side. All others are holding their color fine.
