I have a recently turned 3 year old who loves this playset.  The build took probably 40 hours doing 95% on my own out of a small garage (finding pieces in boxes felt like half this time).  Everything came together relatively easily and instructions were great.  Assembling the turret was the only part that caused difficulty.  The provided screws continuously stripped when trying to screw into metal.  I swapped out the screws for hex head screws from the hardware store and was able to complete much more easily.  Highly recommend to anyone with kids
