ISOTRONIC® Ultrasonic Bird Repeller device, Battery powered portable Bird Deterrent, Scarer - Pack of 2 Pcs.

Both units have been turned on and the birds are still settling on my roof and sat dish blocking the TV signal. I have gone for the old approach by using spikes, they work. In my view this product is useless and not worth the money.

I was getting a load of birds poo on my new car, and picked the at the rubber from the car window seal. . Never happened before. Put two of these out pointing to the car. Within a week they stopped attacking the car. Of course it could be coincidence if the nesting season had finished at this point. Will know next year

Still not stopped the pigeons. I’ll wait and see

The item arrived, I installed the batteries. The instructions says it the repellent reaches 40m2. The birds still keep building their nest, despite two repellents installed, one in the attic right beside the nest and another at the window under the nest. It's a waste of time and money. I do not recommend.

They have definitely had an effect on the local bird population. I bought 2 and one has got water ingress so has stopped working, which isn't very good!!

Difficult to set up and I will know better if it works in a few weeeks

Doesn’t work as been promised the pegeon bird’s sleep next to it It’s rubbish waist off money Don’t by

Made well and sturdy. Designed more for the the large garden. Took a day or two to work effectively with a extremely high pitch sound which can be heard by human ear when quiet. Battery life can last up to two years Worth the value for the money.
