Exactly what I needed
Size: CRV (2023-2025) 1.5L Gas
I'm not sure how much there is to say about an automotive cabin air filter. I double-checked the specs to make sure this was compatible with my car, ordered the filter, then installed it. It fit, it didn't have a weird smell, I haven't thought about it since. That's exactly what I want in an air filter. Five stars!

A perfect fit.
Size: 26" 26" 13"
It's not often you get to say 'perfect' about almost anything, but this is one of them. The product was a terrific price, it came in a day, was packaged perfectly, was easily removed from clever packaging, it was simple and obvious how to install, and it fir perfectly, both front and back. True OEM fit, feel, and finish. Like I sad, peeerfect for my VW Touareg. As advertised. 5-star. And I ask again, how many 5-star ratings have you given? This is my first and I'm n old guy. Been doing business on Amazon for decades.

Fantastic blades at a great price.
Size: 22"/20"/14"
Perfect fit and work better than the expensive brands, like rain x. Have had no streaking issues as I have had with many inter brands.
Great price for the 3 pieces as well, and highly recommend.

easy install, cleans well
Size: 26" 20" 12"
took less than 10 minutes for front and back replacement: a lot of that was spent on figuring out how to get rear wiper removed. perfect fit. by geometry, installing passenger front wiper was a little more tricky simply because of the reach issue [and I have long arms]. but that's not a problem with the wipers.
windows were covered with pollen. using the spray and wipe option, they cleared up beautifully in one pass.
note: OEM has a heavier bow with a joint in it to adapt to window curve. this wiper has a lighter, more flexible bow with no joints, but hugged the window perfectly. it may help that it's almost 90 F outside.
waiting to see how it does in colder weather and with snow, and to see durability.
