⭐⭐⭐⭐⭐ Perfect fit and clears well
Size: H309 (12")
I purchased the BOSCH H309 OE Specialty rear wiper blade as a replacement, and it fit perfectly. Installation was quick and easy, and it snapped right into place without any issues. The wiping performance is excellent. It clears the rear window smoothly and evenly, with no streaking or skipping. Even in heavier rain, it does a great job keeping the glass clean and clear. The build quality feels solid, which is what I expect from Bosch. After regular use, it’s still performing well and hasn’t shown any signs of wear. Overall, this is a high-quality rear wiper blade that works exactly as intended. Easy to install, great performance, and reliable quality. I would definitely buy it again.

Great Pick
Size: H326 (13")
Fits perfect for my 2006 Hyundai Santa Fe. Doesn’t leave streaks and doesn’t make much noise compared to my old one. Had an awful storm and it kept up well and was shockingly durable. It offers good coverage on the rear windshield and is clear enough that I can still see.

Easy Install, Clear Wipe, So Far So Good
Size: H354 (14")
I put this on a 2016 Honda Pilot, and installation was quick and simple. It took me about a minute to remove the old blade and snap the new one into place. Your time may vary depending on how familiar you are with your rear wiper setup, but if you’ve swapped one before, this should be straightforward. It’s only been on for a couple of weeks, but we’ve had a good mix of rain and car washes during that time, and it’s been wiping clean with no streaks. No squeaking, no smearing. Shipping was on time, packaging was standard, and the price felt fair compared to other options I looked at. I know some Honda forums recommend just replacing the rubber inserts and sticking with OEM parts, but I didn’t know what brand was on the vehicle before. I ended up choosing Bosch mostly based on price and availability. For a rear wiper, it felt like a low-risk upgrade, and so far, I have no complaints. The only thing I’d point out is that these blades come with a 30-day warranty, which doesn’t leave a lot of room to see how they hold up over time. That said, after the first couple of weeks, everything looks and performs just fine.

Fits my Honda Fit 2012 rear wiper
Size: H354 (14"), Size: H354 (14")
Easy to install and fits my Honda Fit 2012 rear wiper. The wiper has a low profile but looks like a nice beefy wiper. It wipes quite and smooth.
