I think they're hype. I've seen them in car shops too. Personally I do not see any reason why we need two or three blades. One is enough. Yes we change the blades periodically, but one at a time is enough.Have you seen these wiper blades that have, like, a double or a triple edge to them? I saw an ad on television, and I've seen some in the stores. Is it hype, or are they really better?
