Have had this for a couple years now, our kids love it and so had every kid that's been to the house! Much easier to assemble than wood sets I've done in the past. 
One thing that I've noticed, is with the slope of the ladder, smaller kids who have climbed the it for the first time, freak out at the top trying to get across the gap from the last rung into the clubhouse. An additional rung at the top would solve that, and I've debated buying one and drilling my own holes to add one. Also wish they sold matching touch up paint for the metal pieces. 
Still, overall, we love it and highly recommend
