Good quality.
Size: 15"+15"+13"
I needed to replace the wiper blades on my Jeep Wrangler JK, so I first went to a local auto parts store. The prices were pretty expensive, and they didn’t even have the correct replacement for my rear wiper blade. That’s when I decided to order the UTOBOO 15"+15" Windshield Wipers with 13 Inch Rear Wiper Blade Replacement online, and I’m really glad I did. The set arrived quickly and included everything I needed for both the front and rear wipers. Installation was very easy and only took a few minutes. They fit well on my Jeep, and the blades feel sturdy and made from good-quality materials. After using them, they wipe smoothly and leave the windshield clean without streaks, which is exactly what you want, especially in rain or dusty conditions. Overall, this is a great value compared to buying individual blades in-store, and it’s especially convenient since it includes the rear wiper replacement too. I would definitely recommend these to other Jeep Wrangler owners looking for an affordable and reliable option. ------Tip, don't forget to take off the green plastic, If you check the comments many people argues that the wipers don't work but in the pictures you can see they did not take off the green plastic protector. ----
