Fixed semi circle, no faff assembling, just clips to canister neck. Well made, no sharp edges, light at 90g, takes no space, nests around my 800ml Andes cook pot and inside the 1000ml pot.
Used when quite windy, speed not measured but not a gale, very effective.
Bad points at 10.5cm tall, too tall for my 9cm tall (with pot stand out) MSR pocket rocket. As a semi circle it only supports half my pot, making it unstable. Thus 3 stars.
I like it, just cut shield wall down to fit my pocket rocket.

Good quality. Fits easily onto canister. BUT 10 large holes round wall base, presumably to keep canister from overheating and these allow wind in. In slight wind, flame blown to one side. Not tested in high wind.
Find out how it performs in high wind before buying.
