The cover was easy to set up but my only problem is that the cover is not waterproof as shipped. So the first medium rain I got a fair amount of water dripping through. I was able to alleviate some of it by raising one end of the pergola a couple inches by putting bricks under the posts on one end which tilts the whole thing subtly and letting the water drain on one side.
The other thing I would highly recommend is to waterproof the fabric BEFORE installing it. Having to take the whole top cover back off to protect the fabric was a pain.
