I was driving behind a Highlander tonight and noticed that the rear window wiper appears to be exactly the same as the one on the Prius. I assume the wiper on the Highlander does a better job because of the placement and size of the rear window. I'm not complaining, just making an observation...
It's raining today in the northeast. Driving in I didn't even need to use the rear wiper. I use Rain-X on all windows except the windshield and visibility is fine. Give the product a try; it works well. Don't forget the mirrors and headlights; it help keep crud off them also. I found that Rain-X on the windshield causes buildup which clouds with time from mirco-scratches caused by the constant swiping of the wipers. So far, I haven't had problems with rear wipers; I just don't need to use them that much.
