The trademark of genuine Haobo hinge is clear, delicate and even, while the trademark of fake Haobo hinge is relatively rough. Lift the rotating cover. If there is a trademark on the raised side, it is genuine, and if there is no trademark, it is a counterfeit product. German Haobo's trademark is HOPPE, and Shenzhen Haobo's trademark is HOPO. Pay attention to the difference.
