Easy to use: With optimized functionality and simpler operating logic, this digital clock is very easy to use. Decorative clock: Can be easily mounted on the wall or used on a table or desk with the built-in stand. Battery operated so the position can be adjusted. (Requires 3 AAA batteries, not included). When the clock is installed on the base, it's an excellent clock for the office, bedside table, dressing room, bedroom, study, or kitchen. When the clock is without the base, it can be wall-mounted using the hanging hole. LCD display: Easy-to-read time, indoor temperature, date and day of the week, accurate to the fraction of a second. The large LCD screen is located within 30 feet of the room, and the time is visible at a glance. The modern design is not only very suitable for a desk clock but also makes a great room decoration.
