Familiarity: I've put it through the wringer
I've used these for three seasons now and have the fender placement down pretty good but still have problems with clearance on the rear which is so close that sand quickly builds up while riding in the road conditions I need it the most, that is post snow roads that have been salted and sanded. For that reason I have switched to a rear mountain bike fender that doesn't work as well but also doesn't require me to stop mid ride and readjust the fender. The front works fine and is the only front, portable fender I have found that is long enough to protect the drivetrain as well as protect me.
My biggest complaint is that the curved rubber compression mounts cause the bikes clear coat paint to rub off, but whenever you attach a friction mount to a painted service this should be expected.
