My now 2 y/o loves to swing, slide, and hide in the structure.  Easy to put together, just make sure you use the correct bolt length or you will have trouble getting the nuts to fit on.  The instructions for the first part don't tell you the bolt length, and they are a different length than the ones included in the extension set.  Black caps for the bolts only fit when you have a lot of the bolt remaining after you screw on the nuts (They did not fit on the bolts on the play structure as they were too short).  It is also helpful if you have a socket wrench or two to make it easier to assemble the bolts/nuts (as the plastic one included is a pain to use with a screwdriver).  Otherwise a great product that works well for my very small backyard.  I was able to put it together by myself while my mom watched my kids.
