I had one pull away from the metal, making it useless. For the 10 months or so that they were on, they worked well. They chattered a bit, though. They didn’t do so well in the snow–snow kind of rolled over the top of them.
I replaced them with Bosch Icon. They don’t chatter at all, they work well in the snow AND they don’t make that “click” when switching direction. Quite neat. Advanced has them 25% off along with their other blades.
