I usually laugh at stuff like rain x, but I was given a bottle of the concentrated juice and a couple gallon jugs. I swear my windshield stays cleaner and clearer. last night it rained, I all most didn't have to turn my wipers on. When I did, one swipe, like a new windshield, clear as a bell. I'm sold. Plus I always buy the Bosch blades. I also always get a new windshield every couple years thru my ins.

 

Lol

 

I actually like it. Gets those last few droplets off that blow up from driving. If it is smearing you prolly need some new wipers. I always use bosch wipers and never had an issue.
