ISOTRONIC® Ultrasonic Solar Bird Repeller device, portable Bird Deterrent, Pigeon Scarer - Pack of 1 Pcs.

Does not work. Seagulls made a nest a few feet away from it. Also they sat next to it. The instructions say to give it a couple of weeks to work, then your outside the return date. Contacted seller via amazon and direct for a refund. Got no reply or any acknowledgement. Load of rubbish. Wanted to give it 0 stars but had to give it 1 to post review

Easy set up and straight to work keeping the birds away. Only down side is the high frequency chirp every 25 secs

First, I didn't trust it.Now, after month, pigeons stop coming.You only need to charge it once and keep it on the sunny side, that's it, no additional charging required. Birds will stop coming, but it takes patience as it will take few weeks to actually work.

I have given this only a 1 star rating not because of its effectiveness but because of the quality of the product.Concerning its effectiveness the jury is probably out, I purchased this in May 2023 and think there was a degree of improvement with the pigeons although it by no means got rid of them totally (I know it says it takes time to be effective but this comment is based on having had quite a few months over the summer).But the product quality is poor.........after just a few weeks the hook by which you are meant to hang the device snapped off and now it has stopped working. I found it was full of water and having dried it out it no longer operates - well only when plugged in, relying on battery power only (which is necessary when it is in the garden) it doesn't work any longer.The instruction manual isn't great either.All in all, not great.

I can hear it and I can see it flashing at night, but I can also see the sparrows roosting in the wisteria where I do not want them so it is not really doing its job.

Best of the three types i got to try,doesnt say much for rest.

Works well very surprised

This simply doesn’t work. I put it in the garden for 4 weeks and it’s made no difference, the pigeons are still there. I’m now sending it back for a refund.
