Hated it. Took it to the dealer last week, and after a few programming issues, got it back today and it's OFF now. Made about 8 stops today and no more turning it off each and every time. I had it on the X3 loaner too... thinking I might tolerate it there more, but no way. At times it was just rough... letting off the brake and it would actually slightly jerk the car a bit... can't be good off and on many times in just one trip of driving, then daily... anyway, love it off and I will leave it OFF!
