ISOTRONIC Ultrasonic Bird Repellent for Repelling Pigeons, Sparrows, Seagulls & Crows – Battery-Operated Bird Scarer for Balcony, Roof & Garden –

The ISOTRONIC Ultrasonic Bird Repeller device is a portable and battery-powered bird deterrent that comes in a pack of two. While the product description claims to effectively deter birds, customer experiences vary. One customer purchased two devices to deter pigeons but found that they did not seem to bother or deter the birds. Another customer reported that the device did not work at all for them, suggesting that it may not be effective against all types of birds. Customers also inquired about the device's compatibility with other animals. One customer asked if it would bother chickens, hens, and ducks, while another was concerned about the impact on their dog's hearing. Both customers received mixed responses, with one indicating that the device did not bother their cat and another unsure if it would work on seagulls. Several customers had specific scenarios in mind, such as using the device to deter birds from nesting under solar panels or in the attic. Unfortunately, the device requires line of sight and does not work well with obstacles in the way. The range of the device is also limited to only 4 meters outdoors. Overall, customer experiences with the ISOTRONIC Ultrasonic Bird Repeller device are mixed. While it may work for smaller birds in certain scenarios, it may not be effective against pigeons or larger birds like seagulls.
