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.

Each year in March April I have had to endure the scurge of stralings nesting in my eves - both sides of the house. I dont mind the birds, but their droppings and those of their yough have caused a problem. Three or four times per season I would have to powerhose both sides of the house. I installed two ISOTRONIC® Ultrasonic Bird Repeller devices, one at either gable. This year - nothing. No birds, no droppings, no hassle. Great job, great product..

We bought these because we have many pigeons that mess up our fences and decking. they seemed to work for a couple of weeks now we are back to having bird poop all over our property again.Maybe it's the position I've put them .or maybe the birds are use to the high pitch noise now.Also my wife and children can hear the high pitch noise, but I can't.

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!!

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.

Product was delivered timely, however the batteries provided with the item were not working both sets, replaced the battery and both of the lights came on so are working, I should get two replacement sets of batteries

No difference as many birds as befor, waste of money

The bird scarer worked within 24 hours there was no more bird mess on my drive. Product stated that you needed to wait up to 28 days but there was a marked difference in a short time. Definately would recommend it.
