We put these on last year after most of the snow fell so didn't have a chance to see if they helped much. We have had a lot of slushy weather lately. Gotta say, they help a lot. Still get some splash on the rockers and maybe the first 30 centimeters up but overall we are pretty happy. Big change from last year. These are from RPM so no drill etc. Don't know if they are available elsewhere or not but would recommend them. We have had bad luck with RPM as far as purchasing but I'm sure somebody else sells these same units. Don't mind the look as they are a little more 3 dimensional.
