The dual power system (solar and USB rechargeable battery) provides convenience and can keep the device running for up to 15 days on a full charge, which suits outdoor use well. The device is designed to resist weather and heat, making it durable for long-term placement in yards or gardens. Installation is flexible, either mounted on a wall or staked into the ground. While it is effective for small to medium outdoor areas, larger properties may require multiple units to ensure full coverage.

While the repeller covers a decent area, its 10-meter range might not be sufficient for very large yards. The product requires continuous use for 2 to 3 weeks to see the best results, so it’s not an instant fix. Also, since it uses ultrasonic waves and flashing lights, some pets or animals might get accustomed to it over time, reducing effectiveness. Including 1 AA battery (in addition to solar power) provides backup, but you’ll need to monitor power levels occasionally. This repeller is a solid choice if you want an eco-friendly, hands-off way to deter dogs and various other animals from your outdoor space.
