First of all I would have to say the graphics on and in the house are great along with the window features. The elevator is a plus and was a big hit. The size of this doll house is impressive and will create hours of fun. With that said, we did run into a couple of obstacles. On step 36 the holes were not drilled to receive the screws that hold the top of the staircase. On step 46 the hole drilled into the end of the front wood support was not drilled straight so we were not able to connect the pocket style bolt until I put it in my drill press to drill a straight hole. These were fairly minor concerns as I had the tools to take care of this. I will warn that it will take about 4 hours for an individual to build this but the results are a very nice overall product. P.S. The Shimmer Mansion is very large, so if you are giving as a gift to be taken home, make sure you have a good and large area in your vehicle to transport it as it would be difficult to dissemble the house.
