This is not what I would call a 10x12 gazebo. That is the outside measurements which include the overhang on the roof. The actual size is more like 9x11. Installation always takes longer than what they say, especially since there was only 2 of us. Instructions are clear for the most part, though a few of the diagrams were difficult to understand. All of the roof panels had a clear film on them which had to be removed. I get why they would do that, to prevent scratches, etc., but what a pain removing it from every single panel. The roof panels did not always slide in as smoothly as we had hoped. Several panels required significant jiggling around to get them to fit flush.
Anyway, we put it together, it looks nice. See how it holds up to weather.
