Have worked great so far!
We live in the country, so mice are a given. We have cats and a dog, so we don't want to use any kind of poison since our cats have gotten ahold of a couple of mice. If the mice are poisoned and the cat eat them, it would probably be too late for vet care before we realized what happened. Of course we take all the preventative steps we can like not leaving any pet or people food out, putting out pet safe mice deterrent, etc. There are baited snap traps all over the attic, basement, closets, etc. but mice would still sneak into the house. Even our pest control guy said that without poison baiting, it would be a constant battle since mice can get into a home through the teeniest openings and a house in a place where they have a lot of natural predators is a spot mice will seek out for safety. We live across from a nature preserve with several species of predator birds such as eagles and hawks as well as coyotes, foxes, and such. Before ordering, we had no idea if these would work or not. Based on online reviews and pest control blogs and websites, it's a toss-up as to whether or not electronic pest control actually works. These and a couple other electronic gadgets like this have been installed and on 24/7 throughout our house for about a month now, and since then the number of mice seen has gone from one (or heaven forbid, two) a week to zero. None. Nada. None in the traps, none caught by our cats and used as hacky sacks or worse brought to us in the middle of the night as a present. The ONLY thing that has changed is the addition of these electronic repellers. Our cats might be disappointed at the reduction in play toys, but we are not and neither is our pest control guy. When we set these up, he wasn't able to tell us if they'd work or not, but even he is impressed that after four/five weeks of having these, there has been a major reduction in mice even though it's freezing outside and the mouse population should have gone up inside as mice seek shelter from the weather. These units are easy to operate, and we set a reminder on the calendar to change out the batteries every five to six weeks. Our pets are not bothered by the lights or the frequency of noises put out through the speakers. They are small enough to be put almost anywhere, and are not intrusive in the least. So far they have been a massive help in our fight against Mickey trying to shack up rent free.

Useful for mice and not packrats
Maybe a hard winter is coming because this is the worst year for mice in vehicles at our ranch, we've ever had. I received 1 unit that wasn't working, Email for the company bounced. Contacted the seller who responded quickly, was helpful, and replaced the defective unit really fast. they seem to be working well in the vehicles where mice was the problem. Under the hood of a pickup where packrats were a problem building a nest overnight, I placed one in the cab, and two under the hood. The packrats were not fazed. I've cleared 5 nests out in 5 days. Some mice had gotten in the cab of the truck and they seem to be gone. In this vehicle I've added some PAM spray with powdered hot cayenne which should deter the packrats, it didn't. I tried it loose and it wasn't enough of a deterrence. In two other SUV vehicles, mice had moved in quickly. I combined two units in the cab, front and rear, and one under the hood. I combined this with a large Tomcat tin trap that will hold a LOT of mice. Over 4 days, I collected 10 mice in one vehicle and only two were found alive. In the other SUV, we caught 6 over 4 days. I used Tomcat attractant gel in these traps. To remove live mice, I shake the tar out of the container and daze them. Then I remove and dispatch them. This is the best and most successful method we've had with this problem. It took this combination to make any headway with the problem. Imo, these traps should cost about $10-$11 as you really do need to use more than one. I just strategically place them under the hood and remove them to the inside when driving any of the vehicles. Our air intakes have hardware cloth over them before the air filter to keep the mice out. I give this product 5 stars since it does seem to work on the chipmunks now. It does appear to work well on mice and chipmunks. You have to be a little patient to clear them out, imo. Being battery operated is a real plus and I can see IF I mounted it properly, you could still change the batteries without removal. The ones inside the cabs didn't shut off when driving, so I just shut them off, then turn them back on when I park. The Vendor/company, I now give them 5 Stars. I contacted them and they responded quickly and well. The only success I had with Packrats was to set rat traps and I cleared out a nest of 4. Since clearing out the mice, they haven't come back. This was the 1st time in our years here, that packrats showed up here. If you have serious mice problem, consider adding the Tomcat Tin Cat traps and use the Tomcat gel to clear them from the inside of the cab. I'm using 20 of these devicess overall. The batteries are lasting and they're working. 7/9/20 Update- since my major problem was NOT chipmunks as it had been in the past, but a new one- packrats, I upgraded my rating to 5 stars to be fair to the vendor and removed the negative language concerning chipmunks.

effective under car rat repeller
We had expensive repairs to three cars from rat damage. Have had no damages since we started using these boxes (one under each car). The lights flash brightly at frequent intervals, and I think that light does the trick. My research showed no benefit from the ultrasound (Can't hear it, but I assume its there). So, it works! Minus one star for relatively short battery life. I'd be willing to pay extra for a rechargeable battery.

A good concept, but hard to install in the engine compartment
After repeatedly finding evidence of rodents or some other animals in my car’s engine compartment, I looked for something to repel them, and found this. Powered by C batteries, it alternates between bright flashing lights and ultrasound to create an environment said to repel such critters. I like the concept, but found the device nearly impossible to install in the engine compartment of my Acura. The only place I could put it was to attach it to part of the support structure for the car battery. I’ve been using it less than a week, and it seems effective. There has been no trace of any animals living in my engine compartment since I installed the device , and also sprayed the engine too with a rodent repellent. Time will tell. The batteries are said to last a little over 60 days. To replace the batteries I will need to remove the device, then reinstall it. That will be every bit as difficult as the initial installation. I imagine the installation could be much easier in many different cars — but that’s not the case here.

Product Did Not Work!
I live in a heavily rural area were mice, rats, squirrels and other rodents are present. This product did not work in the slightest. On the 3rd day there was nuts, droppings, leaf's in the engine bay. The only solution is honestly peppermint spray. I took a different approach from what others have done. I cut 3 small pieces of fabric (Old T-Shirt) then drenched them in peppermint and placed them in 3 locations, 2 on the sides and 1 in the middle of the engine, this keeps out rodents for 1-2 weeks very consistently.

It seems to work at first….
Easy to use. I have one under hood, one on passenger side of front seat and one on floor of rear seat. These along with two no-kill mouse traps to discourage the critters. So far they appear to help. Time will tell. The seller is great…I had a question and was answered promptly in detail. Customer support is commendable! ADD on to review. After 3 weeks of use I’m catching a mouse a day…Thinking the mice get used to the noise and flashing lights…if that’s the case the devices are useless. I have the device in front of the trap and they are walking right past the lights and into trap. So not sure where to go from here!

Keeping the squirrels away
This is our third one we purchased since we found them since they work so good. We use them to ward off squirrels.

Seems to work great, may also double as extra security from unwanted human access
I've had it several weeks and haven't seen any sign of the mice who previously built a gigantic condo on top of my engine. It has a strobe lighting effect, and makes noises that sound like the car is wired for extra security from humans who might also want to break in. It comes with parts to attach it to the inside of your vehicle, but I can't find a suitable place to attach it - all the places that look like they might work get too hot and I'm worried they might melt the plastic, at the very least. The device is too thick to add just anywhere under my car's hood. As a result, I've had to place it in a precarious position under the hood, and remove it every time I want to drive somewhere. And I ordered a new one today, as of course I forgot about it completely and it fell out somewhere on the highway. At least that section of the highway will be well protected from mice!
