Excellent front wipers, rear slightly shorter than expected
Size: 22"+21"+11"(U/J Hook), Size: 22"+21"+11"(U/J Hook)
I purchased the 22", 21", and 11" windshield wiper blade set for my 2017 Jeep Grand Cherokee. The front windshield wipers (22" and 21") work perfectly—smooth, quiet, and they clean the glass very well with no streaks. Regarding the rear wiper (11"), it does work properly and gets the job done. However, it is slightly shorter than the one I previously had installed. To be fair, I did not measure my old rear wiper, but it appears the one on my vehicle was a 12" blade, even though this listing specifies 11". Overall, I’m satisfied with the performance, especially for the front wipers. Just keep in mind that the rear blade may be shorter than what you currently have installed, depending on your setup.

Nice wipers
Size: 26"+16"+12"D(U/J Hook)
I got the right ones. Checked and checked again. For my husband's subaru crosstrek. The front ones fit perfect. Installed super easy. Work nicely. Had alot of rain to check them out recently. Now the back one. Does not fit. Not sure what is wrong with it, but 2 out of 3 is good.

Finally, no more streaking and squeaking.
Size: 26"+16"(Top Lock)
Bought these a few months ago for my boyfriend’s car. It was for the purpose of replacing the OEM model that initially came with the car, as the squeaking was driving me nuts. Matching the pair to his car’s make and model here on Amazon was easy. The installation was easy as well, as they simply lock in with no difficulty for me. And they look fine as well. They’ve held up the last few months in the bitter winter here in the northeastern seaboard with no issues. No squeaking, streaking, or scraping. The material seems sturdy and of good stability, not flimsy. Definitely directing him to buy this brand again when they eventually need changed out.

Great price and perfect fit.
Size: 26"+20"+12"B(U/J Hook)
All three blades worked great for my 2023 Grand Cherokee. Well worth the money! Make sure you know how to take the old blades off! I had issues with the rear blade, but finally worked it out. The rear blade is 12 inches long, but the factory blade was 10 inches, presumably to clear the roof camera. FYI the 12 inch blade works fine.

Easy Install and Skip Free
Size: 19"+18"+10"(U/J Hook)
This is a good kit - the second one I bought for a different car. Wipers seem to wipe ok. That is if you first remove the little blade guards that come with each wiper, just like the ice skaters use for their Olympic level blades. And having all three blades (two front and one back) ordered specifically to fit the car, I didn't have to guess and take multiple trips to AutoZone or Advance or O'Riellys. Sometimes the reviewer bot likes to know about some specifics as well. So . . . these fight a great battle to resist rain. And with a lever inside the car, these wipers are easy to use once installed. They are really fast when they slide out of the box. Having had some cars where the wipers fell off, I can attest to the safety that any wiper gives the driver, regardless of it's durability or speed. So I look forward to the safety these wipers will afford over having metal arms scratching across the windshield like fingernails on a chalk board.
