Bosch 4816 Evolution All-Season Bracketless Wiper Blade - 16"

The Bosch Evolution wiper blade performs excellent. The wiper maintains full contact through the harshest downpours, and won't clog up with ice. It is easy to install, features quiet operation, and looks great. The downside of this wiper is definately the price, and it is designed to stay that way! The rubber insert (which is the only part that wears out)
can't be replaced. The symptoms of a worn insert are the same as with any wiper, chattering and skipping. When mine wore out, I took it apart (not easy) to examine the design, and found that it is obvious that the wiper COULD HAVE been designed to use replaceable inserts, but wasn't! Bosch's product designers certainly knew what they were doing: boost Bosch's profitability by designing an expensive wiper that must be completely replaced when it wears out!
