Nearly does the trick, where there's a better model option. Wished I had purchase the higher grade model, for this model doesn't wipe as well during moderate and heavy rain. However, for the price I got what I paid for, with my history of this brand, knowing it will have a bit of useable life. It was a fit...Actual replacement. Easy to install. Smooth wipe, for there's no squecking.

Efficient and affordable

Size: 26" and 20", Style: Pack of 2

These were a perfect fit for a 2023 Toyota Sienna. They clean the windshield with no streaks, exactly as they should and I don’t notice any additional noise. Installation took about 3 minutes, and was a little tricky but not impossible.

The wiper blades were easy to install and is doing an awesome job thus far. The fit is perfect and they glide smoothly across my window. Great material and was definitely a good purchase.
