This product works very well. I make a 12 hour round trip in the car once a month. It is dismaying how often part or all of that trip is in the rain. I diligently replace my wiper blades and clean them often but still I am not satisfied with my vision through a wet windshield. This product causes the water to bead and even without wipers the windshield has increased clarity, particularly if you are going over 25 or 30mph. Note that even following the application instructions, you need to vigorously wipe the post application haze off. I apparently did not wipe vigorously enough and my windshield looked cloudy. After doing a more vigorous wiping, I was quite pleased with the results. It definitely provides more clarity of vision and thus provides a safer ride.
