Pestbye® Ultrasonic Smart Link Cat Repellent System - Solar Powered Motion Activated & Waterproof - The Ultimate in Cat Repellers with Ground Stake

I initially got 1 of these and put it up in my garden. Within a week I noticed the foxes coming back. I was about post a negative reveiw with video evidence but I couldnt find a single recording where the fox was in front of the device. The sly foxes seems to be going behind the device without triggering it. So I went ahead and bought 2 more, set them up together so as to have no blind spots. Its been more than a month since then and so far no sign of any foxes. I think this has finally worked for me...the days of fox poo cleaning are finally over.... Hurray!!!

I bought these a while ago to ward off neighborhood cats constantly pooing on my artificial turf. I've had to experiment a lot with the positioning of the devices, the frequency & sensitivity settings, RF link and delay on/off, flash on/off, and I've now settled on a combo that works well and I've not had any cat poo in the last 8 weeks. The cats initially would poo in a 'blind spot' not covered by the devices, so I knew the devices worked and I had to get more devices to cover the blind spots. I initially turned the flash on, RF link to all 4 devices on, sensitivity on maximum. That worked well but the devices were constantly activating with any slight motion, and that drained the battery quickly and I had to charge every 4-5 days or so. Whenever I forgot to charge the devices, the cats would come back and decorate the turf. After much experimenting with the settings, I've settled on the lowest sensitivity, FLASH OFF, RF LINK OFF, DELAY OFF, and It's been 8 weeks now since the last poo, AND since I last charged the devices. The product manual does say to experiment with the settings and positioning of the devices, as long as you're willing to put the effort in, you'll reap the rewards

Useless piece of kit. Cat still fouling garden without this useless device deterring the cats. Does not even deserve a zero star.

Works with the right settings, but eats through batteries, especially during the winter. Using lithium ion rechargeable and they run out every 2 weeks

No more cat poo on the lawn. Worked from day 1 Can recommend

I set up the Pestbye Ultrasonic Cat Repellent in my garden, and it’s been working really well. The solar-powered design is convenient, and the motion-activated ultrasonic pulses seem to keep cats away (most of the time) without bothering other animals. It was easy to install and hasn’t needed much maintenance. For the price, it’s excellent value for money and a simple way to protect outdoor spaces from unwanted visitors. It should be noted however that to start with, the pesky visiting cat wasn't bothered at first, but I had to get the frequency correct which took some trial and error before it became useful.

Like many writing a review here I was desperate for a low maintenance solution to deter neighbours cats from fouling on my lawn. This is not it. Don't let your desire for it to be trick you into buying this product. They have a terrible battery life of a couple of days (even with solar), and the deterrent effect on cats is negligible, if there's any at all. Cats are just too smart to fall for this repeatedly, sadly, and even if it did work, you'd have to change the batteries so frequently it wouldn't be worth it. I have four of these, and now they're just garden ornaments.

No more pooper scooping, fantastic. Highly recommend
