Compared to similar products on the market, the overall appearance is smooth and simple. Every detail is refined, even for the screen printing on the fingerprint cover. We have optimized its position with the fingerprint panel, to make it intuitive for users to register the fingerprint. When observed under the sun (9:30 in the morning with good weather, D65 color temperature), the two materials of the TPU shackle and the lock body shell transition naturally, with little color difference, allowing a more enjoyable user experience.
