We've owned this for 22 months (only one summer) in central Florida and it is 'shot'. The bronze color has become a greenish-grey and the material has become so brittle that it breaks if you touch it. I've included some photos.
Unfortunate because it's a great piece! I don't know if I got a bad one - the other people answering this question had more positive experiences!
