Advantages of 5 in 1 Multifunction Ultrasonic Pest Repeller
Function Advantage
5 in 1 function: Coil Electromagnetic + Ions + Fixed Ultrasonic + Variable Ultrasonic + Led light
Materials Advantage
1. Plastic Horn: Most of the products on the market use a
paper horn/buzzer, but we use a plastic horn so that the
sound pressure of the product will be higher, then it repels
the pest more effectively, and it has longer service life.
2. Coil Electromagnetic: The electromagnetic waves can reach
deeper even into walls, cracks, and crevices throughout your
home or office to repel pests. It makes the working range wider.
Most of the products on the market use a transformer
electromagnetic, but we use a coil electromagnetic,
which is better.
