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.

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.

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.

This productvis clearly marketed as outdoor product, however its not weather proof, I ised it outdoors as directed on the leaflet and the rain as it happens came in and water got thriugh the speaker part of the product rendering the device useless and broken.If you release something hich is meant to be used outdoors you should make sure that all seals are properly in place. I also noticed there is no seal around battery compartment cap which is definitely a poor design choice for any outdoor product.

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

No difference as many birds as befor, waste of money

Have not seen any birds since installed on brick wall opposite patio.Easy to assemble. 6 batteries provided. Switch on and good to go.Noise not audible but red indicator light flashes to show its working
