This thoughtful design was developed for Chinese multi-member families. Traditional locks are not based on user behavior and requirements, are often hard to use and configure, and most of them use zinc alloy with rough craftsmanship. Key design innovations of the E-lock are convenience design and delicate craftsmanship. Input layout and setting UI are based on consideration of the family's daily behavior, and the gradient body shape smoothly supports user input via fingerprint or code. The body is made from a single piece of extruded aluminum, which exudes a sense of quality and delicate craftsmanship.
