It looks and feels well made and fits easily withput too much loose material. There is a drawstring around the bottom, but to increase the security I also put a "bungee cord" around the bottom of the cover and the legs of the Chimnea, and a second bungee cord at the lowest part of the chimney, where the Chimnea starts to flare out.
In very strong winds and stormy conditions the cover has remained in place and protected the chimnea.
9 months on the Chimnea still looks good.
I would recommend spending out on a good cover if you buy a chimnea.
