The Big Cheese Mega-Sonic® Solar Cat Repeller – Effective Humane Alternative - Professional Motion-Activated Ultrasonic Cat Repellent for Gardens UK - Outdoor Solar Powered Deterrent

So I don't have cats so it is annoying when you go outside and discover that cats are doing there bushes in your garden I purchased this and it was great it is very effective it was easy to assemble and did the trick the battery life is good and the design is small and compact and the cats so not like the noise so it has really helped

I've had a few different IR cat repellers and, to be honest, none of them are exactly great. This one, however, is just pathetic. First you want to charge the batteries. Unfortunately it will only trickle charge from the mains adapter. I gave up after 48 hours of charging and removed the batteries to charge. As with most other models, the batteries are a very poor capacity. If you were to swap them for some decent ones, you'd have to wait a week for a charge using the adapter. There are no controls on this device. Not necessarily a bad thing as the knobs on others allow moisture in and they fail after a year or two. This just has an on/off switch behind a rubber diaphragm, making it moderately weatherproof. However, the sensitivity is way too high. During the day, the sun shining on anything within 20 feet of the device will set it off. Blades of grass or leaves waving in the wind, heat shimmer, etc. It just spends all day triggering. Which flattens the batteries in no time. So I thought I'd be clever and switch it on only at night. Maybe the solar cell can charge the battery during the day. Imagine my dismay when I watched a cat walk past this device in the dark and it completely failed to trigger. The one thing it is supposed to be sensitive to, it isn't! If you want an IR cat scarer, get another brand, these are useless.

When they have enough charge, they do the job - no cat poos.. I find the solar panel is inadequate to keep the batteries topped up so have to check they work, if they aren't working a 5 hour offline charge is enough for another few weeks... The danger is you miss them not working and the local cats leave you presents... It has happened a couple of times now..

I have four cats. Two of them regularly do a Houdini over a very tall fence and I wanted to deter them from the adjacent road so bought two of these. For one cat it works a treat as she hears it and scuttles back towards the house - the other one sniffs it, ignores it and walks straight past it into the area next to the road. So I can’t give it more stars. It does say it can take a while for full effect but this particular cat is oblivious and undeterred. She’s not deaf - hears a food dish at 1/4 mile away but we’ve tried everything to stop her short of electric fencing. Maybe that’s next!

Cats do not venture anywhere near my garden now. Need to remember to turn off when the dogs are visiting or it will cause them some distress

Thought it worked at first as the cctv recorded the cat startled for the first time when it walk past the device in the garden. Another cat walks behind it now to avoid triggering it. I’ve walked past it and see the red as light showing it detected my movement so the motion detection works. Only had it under 2 weeks so will check and provide update later on weatherproof and water resistance of this device. Update: useless cat deterrent. Cats are back and walk past or straight into the device. Does not work so waste of money. Not fit for purpose. Wonder if can get money back if it does not meet its attended purpose?

Really does work, it keeps cats away. Do you do one for humans 🤪
