I replace my wipers annually, so I don't need to spend a bunch of money on the countless gimmicky wipers that are out there. You used to be able to find Rain-X wipers just about anywhere, but the marketing morons pushing the gimmicky crap have pushed these out of stores. I am please to have found them on Amazon. I am also pleased to find that they are on Subscribe & Save. Most of my vehicles use the same size wipers, so I can buy these throughout the year and replace them when they show up instead of trying to remember when their year is up. I have always liked the performance out of Rain-X wipers. I think they last all year, remaining flexible the whole time and stay silent. That flexibility make them very effective at wiping the windshield. The cost for the wipers was great when they were around $6, but the greedy corporations keep raising prices, so now it much more. I think the value is still there, but the design has not changed. Still good, reliable quality. The size is accurate. The installation is easy. There's instructions if you need them that are easy to follow.

Yes good choice

Size: 22", Style: Pack of 2

Perfect fit and they work great! It's been over a month using these and I would consider purchasing again. The wiper blades on previously looked a little bit more sharp but these outperform them by a long shot.

Rain Wipes

Size: 24" and 19", Style: Pack of 2

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.
