Overall a really great experience and playset! Definitely use the Bilt app though! The actual instructions don't have many words but the Bilt app is incredible!
Only complaints are the organization of the materials in the boxes but I could have avoided a lot of that headache if I would have laid everything out. Also, mine was missing a pilot hole that not only threw me for a loop but it also caused another misalignment later in the process. I do not understand some of the organization of assembly and why there is some drilling involved (made me very nervous) but it worked.
Playset is plenty sturdy and very nice looking. I assembled a different brand about a year ago and had many more headaches. I did pretty much the whole thing by myself (not exactly a handyman) over the course of 3 days and it took 10-12 hours. If I would have organized the parts first I definitely could have saved a lot of time.
