Query: Really bad

The rain repellent might work, but the wiper starts skipping all over the place.Not only that, it doesn't last one day until the wiper starts skipping.Rain repellent isn't as good as you think either, because if you don't wipe the windshield while raining, you won't be able to see the front when a light flashes towards you(such as car's headlight from the other side of the road or streetlamp) because the light gets reflected from the rain all over the place.Do not buy.
