Worst Company To Deal with
I reached out to Yolintech via email about compatibility concerns with a failing display and controller. Prior to ordering, Yolintech assured me that I could order the new display with "zero risk" money back guarantee. They never stated that this was a "custom-manufactured" item. On the contrary, they provided a purchase link as an "OEM Replacement". Well, I just received the following response that should serve as a WARNING to any potential customers to STAY far AWAY from Yolintech: "Our Compatibility Guarantee covers situations where a correctly purchased display does not work with a healthy, functioning e-bike system. However, based on the diagnostics and the videos you provided, the root cause of the issue is a faulty controller on your end, not a defect or incompatibility in our custom-built display. Because this item was custom-manufactured specifically for your serial number, it is a unique product that cannot be restocked or sold to anyone else. Therefore, as per our policy for custom-made items, we cannot accept a return or issue a refund".
