The engineering is fabulous.   Goes up on a ratchet easily - very clever design.   Ideally, I'd have liked the fabric to be thicker but simply can't complain for the money.   
It comes with its own cover, and the zipper tag on this came off the first time I used it, but it has a drawstring as well, so still perfectly serviceable.   I rang Wayfair to ask for a replacement cover, but this they couldn't do without replacing the whole thing, parasol included.   That seems quite unnecessary so I said not to bother - and was given a 15% discount for the inconvenience.   Absolutely Five Star service from Wayfair.
