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.

Was worried these wouldn’t work after reading reviews, but had got to the point where I didn’t care anymore as the noise and bird mess were unbearable so willing to try anything.. OMG they have worked amazingly well… i can now relax in my own garden and not have to worry about the birds treating my garden like an Avery…. I love them and may even buy more if I think I need them…

Undecided about this item yet but seems to work

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.

Makes a noise, but has no effect on the birds! They are happy sitting next to it.

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!!

Doesnt workWaste of 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..
