It's not cheap here, but it's not something I'm using all the time, so it's not an issue. It stripped Rejex off the windshield as readily as it did with Rain-X.
I don't use rain-x often enough. It really does work great, especially at night. I made a 300 mile trip one night in heavy rain, and could see much better without wipers. One tip when applying it is, instead of wiping it off when dry, just mist a little water on it, and if buffs off clear.
