The product does not seem to last tough weather condition when outside.  I would be happy to upload photos to show my very torn cover after less than 3 years.  It was torn beyond belief.  I do trust Weber as quality provider, so have taken the chance to buy a new one for the 600 series grill.  I really think they should reimburse me, but since I cannot upload photos from Mac really easily, I suspect that is out of the question.  Doubt whether I will even get a response.
