We just finished putting together our Mount McKinley playset and couldn’t be happier. I was impressed with the wood (all edges rounded, only a couple boards that had some slight warping, no cracks during assembly), the instructions (the BILT app was great), and the final fit and finish. We (2 people) assembled it in about 10hrs and didn’t have any major issues. Strong recommend. 

Also, shipping was incredibly fast. We ordered on a Saturday and it was delivered on Tuesday.
