This was a gift I selected as part of retirement and was supposed to come with a cover, but the cover never arrived...not Weber's fault.  The grill itself was relatively easy to assemble but there are a lot of parts so be patient.  The almost wordless instructions (pictures) we're very clear and helpful.
We've used it a few times and are pleased.  Accessories are available at local hardware's stores, but not the plastic scraper for cleaning the flavor bars suggested in the instructions.
All in all, we don't regret selecting a Weber!
