Smooth and quiet wipe
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow, Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
Swapped these onto my car and they work great. Installation was quick and easy, took just a couple minutes. The wipe is smooth and quiet with no streaks, even in heavier rain. Feels like a solid upgrade compared to cheaper blades I’ve used before. So far very satisfied.

Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
Fit and quality is great. However the shortblade needs to be 21". OEM is26" and 21". Bosch sets 26 and 20". I may have missed, but I didnt t see anyone mentioning this issue. Other than that is perfect fit.

Terrific Bosch blades
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow, Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
These German made wiper blades do their job so well that my wife was impressed. Once you get the hang of it they are one minute to replace. Recommend placing a cloth under the blade to avoid any windshield scratches if the metal wiper assembly accidentally falls down on the glass. Nice to see the Bosch name on the wiper blades.
