So after a few more days of rainy riding, I'm still impressed with the fenders. Some people warned me they rattle, but none of that so far. I still get a little spray on my shoes (no mudflaps, not sure if they help with that) but my pants and shirt stay clean. The plastic is light and doesn't slow me down at all.

I don't have a rack on my bike, and it only has one set of eyelets. So maybe that would be a problem for someone who does want racks, although I'm sure a workaround wouldn't be hard to find.
