This is an overall great set, and you get a lot for the price. Assembly does take time and you have to be extra cautious not to split the wood. We ended up splitting the wood of the rock wall. Power drill not recommended. The number 1 frustrating thing was that you have to open all the boxes to get to the parts you need. Jumping around between boxes is tedious and this is probably for all sets, not just this one. So make sure you lay out all the pieces and components accordingly and have an organization method, otherwise this 11hr build can easily turn into a two full day project.
