This 20-inch ceiling fan is truly a "all-season utility device": in summer, it uses a silent motor and a five-blade design, providing a cool breeze without disturbing those doing homework or watching Tv. In winter, it activates the reverse function, preventing warm air from accumulating on the ceiling, and making the bedroom and living room warmer and more comfortable. The body design is simple, not disrupting the home's decoration style. The intelligent control buttons are easy for the elderly to learn. The durable material is not damaged by children's playful touches, and it doesn't need repair even after long-term use. The remote control can change the wind direction in your hand. The wall-mounted design doesn't take up space. The timer function allows it to be turned on before bedtime and automatically turned off upon waking up. It is suitable for large spaces such as living rooms, dining rooms, and bedrooms.
