The wipers are a perfect fit on the Benz. The Bosch Wipers came with good instructions which made for a easy install. In a heavy rain the following week after installation the wipers worked to perfection. They were quiet, efficent and at a low, low price. Its a Benz dealer product at discount pricing.
