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.

Incredible visibility upgrade for my Corolla!
Size: 24", Style: Latitude Repellency
I swapped my old, streaky blades for these Rain-X Latitudes on my 2005 Corolla, and the difference is night and day. The "2-in-1" feature actually works; after a few minutes of use, the water just beads off the glass, even when the wipers aren't on full speed. They were very easy to install with the included adapters and they wipe completely silent without any chatter. If you're prepping for a long road trip or just want better visibility in the rain, these are worth every penny.

Great wipers!
Size: 24" and 19", Style: Water Repellency
Works very well, leaves the film for the water to bead off which is what I love about it! Still leaves it a little streaky when I us the washer fluid but I don’t know if it’s just the ones I got or not. Still love them because they work!!
