Pestbye® Waterproof Cat Repellent Ultrasonic Repeller Cat Scarer with Ground Stake (Battery Powered)

I cannot sing the praises of this item highly enough. I bought 3 about 4 weeks ago and now have a cat-muck free garden again, and it's wonderful. I have suffered with cats at a number of different houses and tried everything from orange peel to pepper dust to expensive concoctions and never had any real success. I set these up as instructed and it would appear the job is done!I have a dry dusty area under some huge conifers at the bottom of my garden and when my neighbour got two cats they decided it was an ideal place to use as their toilet. I protested to my neighbour and we almost fell out over it, but we couldn't stop the cats soiling, and to make matters worst other local moggies began to follow suit. At least four cats were using the entire area as one big litter tray and the mess was horrendous. I daren't let my grandchildren play in the garden any more (I know from first hand experience that cat and dog faeces can carry some very nasty diseases and parasites) and I could not dig over my flower beds or plant any veg because the cats would use any freshly turned soil with relish. All in all my enjoyment of my garden was spoilt.I saw these and decided that the reviews were good enough to give them a try - after all, I was getting desperate. They arrived within a couple of days so I set to and raked all the disgusting muck up (for the umpteenth time) and cleared the area completely, installed one of these at either end and Hey Presto! No more cat poo! Well, almost none. We had one moggy that was a bit more resilient than the rest but I just turned the frequency up a bit and even he gave up after a few more days!It says you may have to persevere for a few weeks with them before they have an effect but that is not my experience, they've worked almost from the off. I dug over a bed to put some strawberries in , and installed my third repeller there to stand guard over it, and it remains poo-free! Batteries are lasting well too, and they're only some old rechargables that won't work my camera any more!Yes, the battery installation could be easier than messing about with 4 small screws, and yes the instructions are a bit naff (print off the product details on Amazon - they are much better than the instructions!) but other than that these items are a Godsend. I've just ordered another in readyness for digging over a veggie bed, so I've now spent about £70, but it's been worth every penny to get my garden back! I hope they work as well for you.

I love this bit of equipment. My neighbour's cats definitely don't like it. The combination of this and some other measures have given us our garden back. No more cleaning up disgusting festering cat s*** on an almost daily basis. No more having to watch your every step when outside.When setting up this equipment I was impressed with the quality feel. As I played with the sensitivity and volume controls my wife began to complain "Will you stop doing that" or something similar. I was surprised as I could hardly hear anything. When I asked what it sounded like she said that it wasn't that loud but the sound was unpleasant. My 20 year old son heard it differently again - to him it was loud "7 out of 10".There is a battery compartment at the back but this is where a problem lies. A Phillips Size 1 mini cross head screwdriver (much smaller than normal) is required to secure the battery compartment and make a waterproof seal. If you haven't got one of these you can't do the job. I bought a Rolson 15 piece precision screwdriver set (£8). The quality of these screwdrivers is a bit dodgy but plenty good enough for this job and many more besides.The cats definitely don't like this gadget. I use it on the supplied ground spike and keep moving to different places in the garden (the cats don't like that either). If you get drunks passing by the blue light on the PIR will attract them but if that's the case just use it in the back garden.

I recently took-up slate chippings at the front of my house and replaced them with a Cotswold stone. I had no inkling that a couple of months later the neighbour's cat would suddenly decide to use it prolifically as a litter tray - eventually three times in four days leading-up to the installation of my new cat scarer. I read the reviews and chose the PestBye in the hope that this would resolve the problem!It arrived in a plain box (inside the usual Amazon packaging) with minimal instructions. It requires 4 AA batteries (not included) and it is fairly self explanatory to assemble, simply put the batteries in, put the rubber seal around the back and use the four screws to attach the battery cover. I couldn't get the battery cover to be absolutely flush and the screws wouldn't go all the way in and I didn't want to over-tighten at the risk of splitting the plastic, but with the rubber seal I think it should be waterproof (time will tell and I'll update on here if it isn't!).I am using it on a stake rather than attaching it to a wall (the stake was fairly easy to attach and drive into the ground - so that the unit was 4 inches above the ground). As it is only a small area I have reduced the sensitivity to the minimum level (and it still works fine). I am using the dial on the third frequency dot as per a very helpful review further down (which will tell you which frequency is most effective against which pest), it doesn't give any suggestion in any instructions. I have adjusted it so that it covers just the space in front of my house, it can cover up to 80 degrees.I am giving it five stars for the effect that it has had on the cat, who seems to hate it as I don't see it wandering around the front of my house anymore - but I would say the instructions are poor and I wouldn't say that it is fantastically constructed as the back doesn't `fit flush'. The neighbours children can hear it as well, so consider that if you want children to be able to play in that area.Just two points to note if you are buying:Make sure you have 4 AA batteriesMake sure you have a very small cross-head screwdriver to hand - easily purchased from any pound shop or DIY place***UPDATE***I've had it for 2 months now and it has worked a charm, not a single bit of cat mess! I've noticed that another neighbour has recently installed one to cover his lawn. I was told that some older cats go deaf and can't hear this signal - to sure if that is correct or not but the cats nearby seem to be fairly young so it isn't a problem for me.
