Windshield Wiper Sharpener

How often do you change your windshield wipers? In this day and age, it makes us wonder whether it is worth spending $29.99 on a product that supposedly prolongs the life of your windshield wiper blades as opposed to getting a new pair when the old one starts to go bad. DealExtreme is currently carrying these items, and while windshield wipers are not the most urgent things to replace in a vehicle, they’re important to say the least despite the fact that it does not rain every single day although they’d come in pretty handy during the winter season. Do you think they’re worth the effort and money?
