Like everyone else, the assembly was a pain.  The directions are basically worthless which is impressive seeing as the chairs are only 4 pieces - to make assembling 4 pieces confusing isn't easy to do.  You'll also be turning the screws in with the provided allen wrench for like an hour once you figure out how the pieces go together.  

Other than that (and it's honestly a minor issue/annoyance) they're fine quality for the price and are perfect for my small balcony.
