For me it's those windshield cleaner nozzels that emit a stream rather than a mist of cleaner onto the windshield. Which doesn't clean the windshield that well, unless you do it 2 or 3 times. Then the wipers push the excess over to the edge, which catches the air stream of the car and sprays it into the cabin...

There were more than a few issues that I had with mine but the thing that I disliked the most was when the water dumped all over my feet from the condensation build up in the AC system.
My garage is no where near as pretty with out it and I do not get as much attention (good thing sometimes ). But at least my feet are dry.
