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.

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.

### ⭐⭐⭐⭐⭐ Bosch quality as expected
*by M***K on 6 February 2026*

Always use bosch aero twin and have never had any issues, sometimes hard to find the exactly correct oem replacements with the correct fitting but once that is worked out, easy peasy to fit

### ⭐⭐⭐⭐⭐ Easy to fit
*by F***E on 22 March 2026*

Perfect easy to fit, no noise and clear screen

### ⭐⭐⭐⭐⭐ The best wipers by far
*by P***L on 19 July 2025*

After making a mistake by buying a different make of wiper blade, I'm back sharpish to using Bosch again. They're by far the best wipers out there. They function exactly how you need them to, with no noise, streaking or juddering. They can be funky to fit on some cars but that's down to the car makers and not Bosch.
