I have used the fenders for a few rides in the rains, and am happy with the purchase. The fenders are nice and rigid when fitted, and don't shake about. I especially liked the design addition of having a slightly larger area of fender on the chain side of the wheel, so as to provide added protection to the chain and front derailleur.
The only thing which is surprising is that only 2 flat washers and one corrugated one were provided with the set, while at least 6 should have been provided according to me. Luckily I had some on hand to use. This is the reason for one less star.
