As a forever German car guy, BMWs for the past 40+ years as a DD, I think well of Bosch. But not their wiper blades, at least not since the days of aircooled VWs from the 60s. They do have several different lines, but do they tell you their cheap ones are junk? Some time ago now, I bought a set of Bosch blades. I'm sure low line, I'm a cheap SOB, but good quality is good quality, right? Two weeks later I trashed them for a set of $1.99 refills from Walmart.
Currently I daily an E39 BMW, 530i. Very few options, weird arms. Bosch, blades only, not refills, for $25 if you can find them and get decent shipping costs. For which they are distinctly mediocre. You know, like the cheap no name stuff from chain auto parts stores. I get 8-10 months out of them.
Maybe, maaaaaaaybe, their high end stuff is better. Or better enough to justify the price. I like their electrical stuff, starters, alternators and much more. But wipers? I can't always avoid them, but I sure try, just due to experience.
