Does what it says
Size: 22" and 22", Style: Latitude Repellency
These are my favorite wiper blades. They install easily on my Dodge Challenger and work well as wipers. But I like the little bit extra of RainX repellency to help water bead off my window in between wiper swipes.

Not streaky!
Size: 26" and 17", Style: Latitude Repellency
These work really well! They are not streaky, which was the biggest thing I was hoping for! They also aren’t too noisy, thankfully! They were easy to install too! I have only used them for a couple of months and so far they have continued working well!

Good wipers
Size: 22", Style: Latitude Repellency
Bought these wiper blades because my wiper blades were old. The new blades lay down a good level of water repellent on the windshield. I actually drove home this morning in a rainstorm and purposely did not turn on my wipers once, and the windshield stayed nicely beaded and cleared, a month after I put the new wipers on my truck. I recently bought my s/o a set for her vehicle. They’re expensive, but seem to be worth it. Very quiet, no chattering, 30 seconds to install on my F150.

Perfect Fit & Easy Install — Replaced Faulty Blade from Another Set
Size: 17", Style: Latitude Repellency
This 17" Rain-X blade ended up replacing a faulty 17" blade from a 5 PLUS set (24"/17"/12") I originally installed.
The 17" from that set had a defective internal adapter — it wouldn’t seat properly on the wiper arm & was extremely difficult to remove. Once I got it apart, the adapter looked warped or misformed. Rather than deal with a full return, I replaced just the 17" with this Rain-X blade.
Installation on the Rain-X was quick & straightforward — it locked in properly with no issues.
Performance so far is solid:
Smooth wipe
No streaking
No excess sound
Good contact across the windshield
Now I’m effectively running a side-by-side comparison (Rain-X 17" vs 5 PLUS 24"/12"), & I’ll update later if anything changes over time.
Overall, this blade did exactly what I needed — simple install & reliable performance.
