Well my Sightlines didn't fare so well in the last snowstorm we had a week ago. For some reason my passenger side was clearing just fine but my drivers side kept icing up. Isn't that always the case? I can't blame that one on the wipers I don't think.
But when I got home I extended the wipers...
There is a replaceable blade option from Toyota. Kinda like the aftermarket concept but it has the Toyota logo on it. Got some for mine and no complaints so far. Can get a part number if you want to check them out.
