Rumor is that the Schindler belts only have a million run lifespan and then the car is shutdown for repair. So make sure you have a rock solid service/repair contract. That being said the Otis Gen2 belts have many millions of runs on them with very few issues. Both of which will probably last far longer than the State mandated replacement period. The government agencies are afraid of change and technology so they are putting very stringent conditions on a lot of new products.
