The only reason I got the Anco Contour Wiper Blades was that they were on sale and my old wiper blades were in bad need of being replaced. I have had these on my car for about three months now and they are still are working as great today as the day I bought them. Easy to follow instructions for installations that you can do yourself. Why pay for someone to put wiper blades on when you can do it yourself not to mention that most places that put them on for your charge a price for the wiper blades that is extremely high, usually ending up costing more than double. Save your self the money and do it yourself it will be a lot quicker and save you a good amount of cash that you can use for more important things like ghost pepper hot sauce. I am not sure how long they will last but seem to be holding up well as there is no signs of dry rot in them or any cracking. I am hoping they last me at least a year, anything after that I will just consider that a bonus.
