Longest Lasting (4.0)

Automoblog, 2025

Retailer or affiliate test 5 blades rated

In January 2025, Automoblog evaluated wiper blades by installing them on a test vehicle, driving through heavy rain, and using a 60 fps high-definition camera alongside user reviews to inspect visibility, streaking, noise, installation ease, and durability. Because none of the blades received an official rank, no product came out on top or finished ahead of any other. The models also tested were Rain-X Endura, PEAK Silicone Plus, Piaa Si-Tech, METO T6 Silicone Wiper Blade, and Silblade WB126S Silicone Wiper Blade.

We did notice some streaking on our vehicle, near the very tip of the blades. These blades also produced some squeaking noises while in use.
