The railings are really nice. VERY well made. The instructions were great. We actually got one wrong item, but since we were in the middle of the project, we made it work. The self-driving screws are a bit of a pain-but, they make the railing that much sturdier. The first one took us awhile to put together. But, after that we had three more and they were very easy. The extension was tough, I have to say. My husband had to do a little manipulating, but we got it. It all looks nice and...it's done...
