Wipers that don't smear the windshield.
I noticed that the new Anco blades I got for our other car seemed to smear like the old ones did.
I bought one new Bosch Marathon wiper blade and it wiped the old cars windshield clean.
Not only that but even with the wipers running slow on delay I can now see through the rain drops that are on the windshield.
Now we have them on all of our cars.
There may be some other blades that are as good or better but I have been driving for over 50 years and I have never seen such an improvement.http://www.walmart.com/ip/Bosch-22-Marathon-Wiper-Blade/16817328
