Toyota has been encouraging their dealerships to sell the SightLine Wiper Blades for service replacement instead of the replacement inserts. Lexus is marketing these same blades as "Lexus Advanced Technology Wiper Blades." There is also rumor that the wiper inserts are being discontinued in favor of the SightLine Wiper Blades, but this has not been confirmed.
For my own curiosity I purchased a pair of the SlightLine Wiper Blades to try out. They retail for $19.99/ea, but you can purchase pairs on eBay for under $30 shipped.
Here are some pictures:
From an initial test, these wiper blades look good and wipe very well. They are a little bit noisier than the factory inserts so it will be interesting to see if these SightLine wipers continue to perform acceptably in colder weather once the rubber ages. The fit/finish of the wipers is pretty good, but the locking tab is a bit flimsy.
