## Description

From the manufacturer Optimum visibility in any weather Bosch - Invented for life Bosch offers one of the world's largest ranges of spare parts for vehicle repair. The focus thereby is on high quality and a long product life. This helps to keep people mobile all over the world. For more than 130 years, Bosch has pursued the goal of offering intelligent and reliable solutions to make life a little bit easier every day. Rain or snow. Day or night. Innovative design and technological advancements of Bosch Aerotwin provide excellent wiping performance Consistent, Durable, Reliable Intelligent Adapter System allows for quick and easy bladereplacement. Aerodynamic Spoiler limits wind resistance and wiping noise. Customized Spring Strips, made from Evodium steel, provide uniform windscreen contact and wiping stability, even at high speeds. Patented Power Protection Plus rubber technology ensures wiper performance in any weather. P.P.P = Performance Power ProtectionPlus: for noiseless wiping Thanks to its innovative wiper rubber with patented permanent coating, these wiper blades slide across the windshield more easily. Unlike the graphite coating, this coating does not detach over time. Due to its lower friction coefficient, this wiper rubber features a higher thermal resilience and wipes wet and drying windshields without juddering nor noises. Tested on your car Vehicle-specific tests: for perfect wiping results Each wiper is tested under conditions of practice. Only those wiper blades meeting toughest demands in terms of fitting accuracy, quality, wiping results, performance at high speeds, noise development and ease of installation are offered for the respective vehicle. All weather safety Safe at all weather conditions: flat-blade technology Spoilers prevent lifting of wiper blades. There are no metal frames or joints susceptible icing of humidity and snow. Using synthetic wiper rubbers, Bosch flat wiper blades are also highly resistant to extreme external weather influences such as heat or ozone, among others. Evodium steel inside Evodiumsteel: for a long service life At the core of the wiper blade, a customized spring strip made of permanently elastic Evodiumsteel ensures evenly distributed wiper blade contact pressure at any point on the windshield. This reduces its wear and results in a longer service life.

### ⭐⭐⭐⭐ Great but flat
*by A***D on 31 May 2022*

Really good wipers but be aware they are really flat so the end might be hanging off your windscreen, luckily I could swap a shorter one from the rear to the front left.
