      Fits great and no streaking.
      Size: H281 (11")
      I bought this for my 2015 jeep grand cherokee. Its easy to install, works great, no streaking, fits perfectly, and seems durable. I used rainx before and the rubber fell apart after 6 months. So I'm hoping this one lasts.

      Easy to install.

      Great replacement rear wiper blade for my 2018 Toyota Highlander. After watching a YouTube video on installing this wiper blade on my vehicle, anyone can do it. Thank you You Tube!

      Quality Windshield Wipers
      Size: 17", Style: Latitude Repellency
      These wipers are a solid upgrade over standard blades. Installation is quick and straightforward, and they fit securely once attached. On the first use, you can immediately notice the difference the wipe is smooth and consistent with very little streaking. The Rain-X water-repellent feature actually works, helping water bead up and roll off the windshield for better visibility during heavier rain. They also run fairly quiet compared to cheaper blades, which is a nice bonus.

      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!
