Rain-X - Winter Windshield Blades Review

My daughter received a set of the Rain-X Winter Windshield Blades from her Grandmother as a gift last Christmas.  Strange I know, but my daughter had requested new wiper blades.  She's attending school in eastern Washington, which meant frequent trips over the mountain pass.  She could never be quite sure what type of weather to expect, so a good set of wiper blades was important.  She loved them.  Raved about how well they worked in rain, sleet and snow.  The family all jumped on the band wagon and ask Grandma for wiper blades.  Me included.  Over the last 8 months, on our birthdays, we've all receive Rain-X Winter Windshield Blades from G-ma.  I'll never change to anything else.
