I got all four, but I will have to say in snow and slush, the front ones are worthless.
I end up with more slush on the front of my fender flares than on the bottom side of the vehicle.
My guess, if they were about three inches longer, that would prevent this slush buildup. So, if slush is getting on there, so is salt.
I might purchase some stiff rubber (no pun) and attach to the bottom of each front mud flap, for winter driving. I'll use some small bolts to hold in place, and when in the non-snowy season, remove them.
