Indeed, it makes cleaning the windows in the rain much, much easier and because of this ease, the wipers are not strained, which also helps in maintaining them in good condition for longer. I deduct one star due to the somewhat time-consuming process: clean the windows very well, let them dry, apply this Rain X Rain Repellent with a cloth and not directly on the glass, rub well in figure eights, then vertically, then horizontally, so it gets into all the pores of the glass. Let it dry, which after about 5 minutes leaves a kind of small, faint white haze on the glass, and then with another dry cloth, go over it again to remove this faint white haze and the windows become crystal clear and completely transparent. The process is not the easiest, it requires some time. Plus, it is quite expensive.

It does exactly what it says, with one detail: I don't put it on the windshield. One time I put it on, when the wipers went over it, it left a white film for a second. When you're driving at night and in the rain, that second multiplies and makes your life difficult and driving dangerous. For everything else though, the side and rear windows and the mirrors are excellent. The raindrops don't gather on the glass but slide off and leave, greatly improving visibility.

5 stars from me as well. It made me wonder why I have been driving for so many years without such a product on my car windshield. At speeds over 55km/h, windshield wipers are not needed. If combined with a silicone spray on them, then the result is unreal!

I used it for the rear window since I don't have a windshield wiper. It does what it says. However, you need to apply it approximately every month because its effect wears off.

It is the best there is, having used various ones, I have ended up with this one. It repels rain, providing excellent visibility in rain day and night, after 50-60 kilometers it repels rain and windshield wipers are not needed. You don't perceive the amount and intensity of the rain, and besides the windshield, if applied to the side windows and rear, you have excellent visibility in the most difficult conditions. In freezing morning hours, while nearby vehicles had ice, my windshield had a moisture film. Also, in humid conditions in the morning, the moisture is immediately cleared. I highly recommend it, thank you.

You clean the windshield with Azax, spray it, leave it for a little while, and clean it with a dry cloth.
It repels rain at speeds above 60-70 km/h very easily, you don't even need to use the wipers! Incredible product, I have been using it for about 4 months (depending on the usage of the wipers, it may need to be reapplied, if the glass doesn't have much water, there may be noise from the wipers)

It helps to repel raindrops, but the vehicle's speed must be above 60-70 km/h. Therefore, it is not very useful in the city. Additionally, its application is not so easy because no matter how carefully I spread it and remove the residue, there remains a slight haze on the windows. It requires a lot of rubbing to make it completely invisible.

X RAIN served me well for the use I made it easy to use it lasts about 7 days then it needs another application.

I will not fully agree with the other users. It does the job when applied. And it does a good job. It repels water. However, it has one, I believe, significant problem. When you need to use the windshield wipers, they make noise and "jump" as if something is obstructing them on the glass. Especially in the summer when the windshield gets very hot... I thought it was the windshield wipers, I replaced them with branded ones, applied again and had the same issue, in two cars! I stopped applying it, I washed the windshield well, and polished it to remove it, and after 3 months there is no noise! no problem.
