I used to use Anco. ALWAYS. Never again though. I was driving thru Dallas during heavy rain. Visibility was so poor, I was going 30 in the Freeway because the semi's were churning up so much water. Well, my Anco Advantage something or other blades were chattering when it was only a mist, and when I had them on high, one of them FELL OFF! WTFO!!
I'm going down the freeway, visibility sucks, and the blade fell off. Nice. I replaced with Bosch. Ever wonder why a human's butt crack is vertical instead of horizontal? You know that sound you make with your lips with your index finger? Well, it's so your butt doesn't make that noise when you go down a slide. That's why. That's what the Bosch blades did after about a friggin' weak. So, I got some cheapoes from NAPA, and they work very well. Replace with refills every 6 months, and good-to-go.
