I replaced mine with the rain sensor clip in summer 2020.

The BMW part was something like $800, uninstalled. I got mine replaced with a Pilkington, who I think are an OEM, for $310 installed. It was done in my driveway by an indy installer, recommended by a friend. Safelite and the nearest glass place the dealer uses were $50-80 more and I would have had to take the X5 to them.
