I use the RainX windshield washer fluid in the washer reservoir and get the same results. It even reapplies itself and stays put in the rain.
The best part is when you hit about 50 mph and the rain just beads off and you don't really need your wipers on.
It's a great gift too if you're looking for something that is relatively inexpensive but every time the giftee uses the washer, they'll think of you.
