Have the Aerotwin wiper blades now bought for the second time for the A-Class (W168) and am satisfied since day one. The installation is very simple, even for untalented "screwdriver". My last wiper blades have almost two !!! Years persevered, but now are finally new overdue. The wiper blades run completely silent on the disc and do an excellent job. The price-performance ratio is compared with cheaper supermarket wipers, which are porous and brittle after just one cold winter night, unbeatable.
