I think the title says it all, but I want to write a few more words. The Bosch wiper are generally excellent. There is no real alternative, The A400H is a wiper, which comes in several vehicles to use, at least for VW. The assembly is simple and intuitive, a guide is not required. Is it then in function, there is a clean wiping result. Noise when gliding over the windshield. None !! So disk wiping should be.
From my experience I can say hearus that these wipers last while always deliver a top wiping result. I think it's very important to mention that a wiper can save lives, because who has a clear view to the front and rear recognize dangers earlier. Therefore, always in time replace the wiper. Preferably before the grubby season.
