We are really pretty happy with our play structure.  My two granddaughters who live with me love this thing and play on/in it daily.  Buyers will hopefully realize that this doesn't go together in an afternoon.  There are lots and lots of wood and other parts.  It is also sizable, and requires two people at times for assembly.  The only potential problem with our unit is that when the swings are in use the tower structure flexes back and forth.  Quite a lot, actually.  I was surprised.  I will be adding a triangular brace to the tower from the base up to the large beam to stiffen up the structure (essentially to "mirror" the beam support opposite the tower.  Over time the flexing has the potential to not only loosen fasteners, but also fatigue some of the key metal parts such that they could fail over time.
