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..

Poor instructions and doesn't seem 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.

The units are compact and the instructions easy to follow.

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

Brought this so called bird scarer to install on a small boat on a mooring that had a seagull issue, fitted last night ( one on either end of a small 20ft boat facing inwards) this morning was greeted with a boat full of birds with the scarer having no affect at all ! I have checked they are working and can hear it working but has zero affect on birds , terrible product , avoid ,don't waste you 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.
