I waited for these to come back in stock because I loved the style so much.  I just received them and haven't had them very long, but they seem to be good quality. They have a good weight to them, but aren't too heavy.  They are comfortable.  I like how the entire chair is covered in resin, which I believe will make the chairs last longer and will not be as hot to sit in as a black metal chair may be when it's in the sun.
