I have begun to switch over on my X3. BMW original refills used to be fine when they made them specifically for each model in Germany and for the longest time I was happy with them. Then one day, they switched over to a standardised blade that you have to break/cut, and they're made in Mexico. I'm sure this saves costs but the quality just wasn't there. And after they completely froze over on my last ski trip, I opted to try out the Bosch Icons. I currently only have it on my right side (haven't installed the left) but so far so good.
