I just replaced the wiper blade (300E) and tried a Trico teflon blade instead of the Bosch that I have always used. I just wanted to let all you mono-wiper owners know that I am very impressed with the early results. It seems to handle the angles and dangles that are imposed on it and wipes very cleanly across the comlete windshield. I think it is a new product. The whole blade assembly costs a bit more than the Bosch but the refills are cheaper.
