As a fleet manager in Texas, I was initially skeptical about sourcing wiper blades from overseas until I discovered YTK on Alibaba. The detailed product specifications and OEM certification caught my eye, but what really convinced me was their 27-year manufacturing history, clearly displayed on their storefronts. We met at the Canton Fair, and Mr. Jack is very professional about the production process of windshield wipers. Our first 40HC container order arrived in Houston last spring, just before the rainy season. These blades passed our rigorous salt spray test (we get 54 inches of rain a year here!). . I was even more impressed that when we mentioned our extreme UV exposure problem, their engineering team customized the rubber compound. To other buyers: If you need a reliable wiper solution with military-grade quality control, stop searching. These people even arranged factory transfers for my team during the Canton Fair. Five stars don't rate them!
