Best replacement option for 2025 Tesla Model Y Performance
Size: Combo Pack (26" & 20"), Style: Top Lock Narrow, Size: Combo Pack (26" & 20"), Style: Top Lock Narrow
Outstanding replacement option for 2025 Tesla Model Y Performance (Pre-Juniper), so much smoother than the OEM wipers. Very easy to replace. They seem very durable after testing on all wiper settings. Definitely keep the windshield clearer without streaks. Seem to also have more stability on mounting compared to OEM option. 15/10 replacement for the cost, can’t beat it.

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. ----

Love
Size: 26+20+14"
I recently purchased the AUTOBOO 26” + 20” windshield wipers with the 14” rear blade, and I’m honestly very happy with them. Installation was quick and straightforward, even without much experience changing wipers. They fit perfectly on my car and clicked into place securely. The wiping performance is smooth and quiet, with no streaks or squeaking, even during heavy rain. I also noticed they clear water evenly across the windshield, which makes driving feel much safer, especially at night or on the highway. The rear 14” blade works just as well and was a nice bonus since it’s sometimes harder to find a good rear wiper included in a set. Overall, this set offers great value for the price, and I would definitely buy them again and recommend them to anyone looking for reliable, easy-to-install windshield wipers.

Decent wipers for a great price
Size: 28+28+11
These fit my daughters Ford Escape perfectly and the day after installation, it rained. The wipers work really well and the windshield is now streak free once again and the price was right. Easy to change and look good.
