"I purchased this set over the weekend and put it together in a couple hours. It was a very fun set to build and had some great LEGO design features and details I love about LEGO sets. However, there is one aspect to this set that really made it outstanding. The bridge raises and lowers as you open/close the treehouse. It might be difficult to understand until you build the set, but when you see it, I hope you are as impressed. It is a very fun feature that I love. On top of that, I can see kids playing with this set for a long time. I also purchased the other treehouse set and together they make a great play set."
