We had a nightmare of a mouse problem that sprung up seemingly overnite. We tried all kinds of traps and the mice could not be tricked. We finally decided to try these things, although I thought they seemed like a total crock. Well, we placed 4 of them throughout our 700 square foot studio apartment and that night we heard some intense chewing - we had just filled all of the holes in our walls and so I assume it was a mouse trying to chew its way out - and ever since that night we have had no more mouse problems. It's been months now and we haven't seen a single sign of a mouse. Amazing.

after recieving and using this product, i haven't seen mice in my room. i don't know where they've went and i'm wondering how they're doing. hopefully they have found a nice neighborhood where they aren't being judged for who they are and can live without worrying about being killed. by me. i am a warrior.

I decided I needed to write a review since there are a lot of negative reviews and I believe most of those reviewers aren't using the product correctly. If you watch the video, it simple states the ultra-sonic frequency bounces of hard surfaces and is absorbed by soft surfaces. So if you put it in your kitchen and expect to have it keep mice out of the cabinets, you may be disappointed. If the mice are coming through the walls or from the basement through openings where pipes go through, they may never be in your open space, but protected from the sound by the cabinets or even the walls.
The key to using these is to use them in the areas where mice are entering. And I think doing what you can to plug entry points also is a good idea. Prior to using these, we would have them in our kitchen - visible in the drawers and under the stove. We did what we could to try to plug holes where they may be entering with steel wool. This helped but didn't solve it. We then had our master bedroom done and I put poison in the attic. They ate the poison, but we could also hear them dragging it around in the ceiling above us - it was very annoying having just re-done the room.
It was at this point, we decided to do 2 things. We had an electrician install outlets in the attic so we could cover the attic space with 3 units - enough to cover all our space. We also put them in our basement in available outlets to try to cover our entire basement and garage area (prior to this we just had them plugged in into our kitchen outlet and bathroom on the first floor). I also still keep sticky traps in our basement (in the same spots I've caught MANY before). We do not have any on our first floor since we figured they were traveling in the walls and they wouldn't be effective.
It's been a long time since installing them in the final configuration and we have not had any issues since. No more listening to them in the attic and no more caught in the garage and no signs in the kitchen. So if you are going to use these, take the time to install them properly and also do what you can to block points of entry. The more you can do, the more effectively you'll keep the mice out.

We have a 120yr. old home - planks w/lath & horsehair plaster - that we have lived in for 28yrs. EVERY fall we get mice. We tried everything to keep them out. The spare bedroom ceiling & our living room ceiling was "mouse central" & was so embrassing when people stayed over. This year we bought these pest chasers & we haven't had one mouse yet. NOT ONE! We put one in the basement where we see dropings, one in the spare bedroom, one in the ceiling of the living room (we have a porcelian socket w/plug up there) & the other on the wall they scooted up. The things are very small & buzz gently but the sound is not too bad. We bought them based on Victor's rep with pest control. We are very happy with them. We are shocked but very happy. We have an 11yr. old cat who misses her late night chases but has never shown any signs she even knows the things are pluged in.

I was skeptical about these, but since I could return them for my money back and I really wanted the mice to stay out (rather than to kill them after they got in!), I decided to give them a try. (I bought Model#: M753.) Before I bought these, I was catching 1-2 mice/day in traps. After plugging in the sonic repellers in the areas where I had been catching mice, I left the previous traps set and baited, as a test to see if there were still mice running around. NOTE: Advertising says the sonic waves are not audible to humans. NOT TRUE FOR THIS HUMAN! They make a very loud, continual, high-pitched squealing sound. Luckily, the areas I had been catching mice were in the garage and in the storage area under the stairs where I keep the door shut. So I've been able to block out the noise by having it behind closed doors. Since plugging in the repellers, NOT A SINGLE MOUSE HAS SHOWN UP in any of the traps!! This is a significant difference! It has only been 1 1/2 weeks, but before plugging them in, I would have caught many mice in that time. So it seems like they work great at repelling mice. I would recommend them only if you have an area that is wide-open so the sonic waves don't get blocked (it explains this on the packaging--I have to put them at the end of extension cords to get them out into the open), and only if you can close off the areas where you've seen mouse activity so that the noise the sonic repellers give off doesn't drive you bonkers. Oh, and my cats, who used to stalk the mice, no longer act like there are any mice around, and they don't have any reaction when they're near the doors behind which the sonic repellers are doing their high-pitched squealing. Even though there are a few caveats in my opinion, I give these 5 stars because the mice now appear to be staying away! If mice show up even with these things plugged in, I will update this review because I feel very strongly about it. So if there is no update, it means the mice are still staying away!

I had the product for about two weeks in my 600 sqt ft apartment and it as a precaution and it just so happened that as i watched tv one night i saw a couple of mice run right pass the product, so I AM NOT PLEASED!

oh how i wished this had worked, even just a little. It has been a few weeks since I got them and now Mickey is so comfortable in my home he has invited Mini, Mighty and Speedy Gonzalez to join him in gnawing on the wood work right next to one of the devices. They buzz but that annoying white noise only seems to bother me, not the rodents.

I have a bad bad bad B-A-D mouse problem! I have been killing an average of 6-12 mice a night with old fashioned wooden baited mouse traps. The mice have gotten so brazen and bullyish that often one appears on my living room floor right in front of me and just sits and stairs up at me as though I'm supposed to go get food for him. I caved in and bought a two-pack victor sonic pestchaser and waited until this little ^&*(#@% came out.....upon seeing him I plugged in the unit and he immediately "twitched" and spun around towards me, and took off running! It's been several hours now and I've not noticed one single sound or movement......normally you can constantly hear them chewing and running up above the ceiling. I'll write again in a week or so as I expect any product like this to take a bit of time to be affective.

I got this despite being skeptical and initially not getting it due to all the negative reviews and my negative experience with Bird-X's sonic bird repellent which did not work (it only made an irritating chirping sound). My home had been under recent attack by large rats and I had caught several of them with conventional rat traps. But they kept coming as if an unsavory neighbor was practicing black magic against my family. I prayed and came upon this at a store. As they are reasonably priced and the store had a good return policy, I thought, why not?
I no longer hear the scurrying of rats whenever I check the kitchen at night. A week later I still heard no rustling. The rat that I heard recently before Pestchaser was nowhere to be found. Really. I had also purchased an electronic rat trap as constantly buying rat traps and even reusing them (yes, you can reuse them) had become too costly but I guess that one won't be put to use anytime soon.
For those wondering if it makes a loud noise, you'll be happy to know that it didn't register on my keen ears. And I've been told many times that I have good ears. The only way you'll hear something is if you place your ears right next to it. It makes a slight buzzing sound that is extremely faint.
The product that I purchased has the nightlight which does not have a switch to turn off that function. When you have three going not too far from each other you have too many nightlights going. I do like the nightlight feature as I can walk through the hallway where one is situated without turning on the lights at night to go to the restroom.
I can only surmise why all the negative reviews. Maybe some of them are from people who did not use the product correctly. You have to place them at ground level and clear of obstacles such as furniture or curtains. One of mine would have been behind a curtain so I had a large vase hold the curtain just enough away from the device. It is very important to have a clear path for it to send the sound out. Fabric couches would simply absorb the sound thus nullifying it's effectiveness completely. Also, I placed mine where rats have been seen or have left waste or close to the entrances. Rats move about by leaving urine traces which they use to move about. If you see rat waste, that is the place where they will pass through. I learned that from a post by an exterminator who kindly shared his secret.
It is also very important to leave these devices on at all times. Removing them during the day can do much against its effectiveness as you need to create a constant sound that will make your abode very unfriendly to rats. After a while the rats will either come in only to find the place unpleasant and leave or just simply avoid the place altogether. We had one rat come in but he never stuck around.
Another explanation I can come up with is that neighbors don't want you to know about this so that their rats will have an alternative, your place. Don't laugh. My neighbor is the type that will do just that. He used to park on our property as if he owned the place until we put up a fence.
And yet another explanation is that some people that write reviews are simply competitors who are trying to sabotage another company. I have heard of companies hiring people to write negative reviews against their competitors. I wouldn't count that off.
Finally, another explanation would be that the rats were not bothered by the sound that these devices make. Although these devices do make a range of frequency, they do change their frequency to prevent rats from becoming accustomed to them. But there is the possibility that they are either not bothered by the sound or become immune to it. I do hope that the latter does not occur in my case. I doubt it as the frequencies change.
Another mistake that people might make is only using one of the devices. You need to use all of them. If you only install one, one area of your home will be inhospitable to rats and they will just simply move to the opposite side. Further, you need to have an overall sound stage to make your home unfriendly to rats. They need to get an overall dislike for your home. And that means installing these in key areas of your home. For each person's home, that will be different. A good place to start, of course, is the kitchen area. If you don't have a floor outlet there, just get an extension cord.
I hope that this review helps those who are sifting through tons of reviews and are confused. I don't blame you. I was, too. Unfortunately, these negative reviews may do a disservice to those that could use this unique product. One big lesson I learned is not to believe all those negative reviews. If you see some positive reviews, that tells you something. Even if most of the reviews are negative such as in the case of this product.
It has been a month since I have been using these devices and I encountered one large rat in the kitchen. I cannot completely blame this occurrence to the devices as the doors were left open the whole day due to cleaning. As such, I have lowered the ratings to four stars. So, to those who have a rat problem, be sure to keep doors closed as rats use that opportunity to enter your home.
It has been a couple of months and I have come across a small rat that I have seen in the kitchen. Part of the problem is that my kitchen does not have an outlet at floor level. Using an extension cord is not a very good idea because there is no place to put the device. The kitchen gets a lot of traffic and as such it would be in the way. Otherwise, I have only seen this one small rat scurrying around. I have yet to see a big rat in the house. I will somehow install one of the devices in the kitchen and leave an update at a later time.
Now, after several months I feel that I can give this product a fair assessment. Today, I saw two large rats in the kitchen scampering away when I went to get a drink of water in the evening. As I have mentioned earlier, I had installed the device in the kitchen on the floor level as the instruction states. I have been running these devices for several months now and have not seen an improvement in the rat problem. I have come to the conclusion that there is no substitute for good old fashioned rat traps. They are the most economical way of getting rid of rats. They are reusable, by the way. Don't believe the folks that say that you cannot reuse them. They're probably either too squeamish to empty the traps or just believe the myth that rats can sense danger from the odor of a dead rat on the trap. Nothing can be further from the truth. Yes, some of them are smarter but most rats will go for the bait regardless of the odor. I have used one trap to capture half a dozen rats. You can keep using them as long as they can snap shut. Well, folks, that's my assessment in a nutshell. I hope it saves others from wasting their hard earned money. If it does, then it was all worth the effort.

I received what I ordered and expected (Victor® Mini PestChaser® Ultrasonic Rodent Repellent 4-Pack), in a timely fashion, i.e. within the range of the delivery estimate, and in good condition. Three of the four "Ultrasonic" units I can hear, making them not only questionable but not what is advertised. I live in the country and rodents are a common concern. I was hoping this would solve my rodent issue. It has not. Not even close. The traps are going strong and I cannot say if these "Ultrasonic Rodent Repellent" things are doing anything at all. I am sure three of them are not. The noticeable electrical hum can be hard to take in a confined space like a bath room. I could not and would not recommend this product to anyone.
