Victor M753K PestChaser Indoor Ultrasonic Rodent Repellent with Nightlight, 3 Rodent Repeller Mouse Deterrent Plug In Devices

I have used these for many years. They do not get the mice out of your house. You need to use mouse traps for that. Once you get them out, they are very helpful in keeping them out. You have to be sure to seal any entry points where the mice get in. They are not 100% effective, but they are worth buying because they do help. You just have to have realistic expectations.

I have at least one in every room. I know they work because I referred others and they saw the magic too. Speaking for myself I put one on the kitchen wall that shared the living room wall. I no longer hear mice going from behind the dishwasher up the wall. The night light has been a blessing because each room has enough light to save me from flipping the switch after I am in rest mode. Saving me on electric costs. I sleep in a room with one and I hear nothing from it.There is something I am not sure about. In the craft room, I hear a constant mumm sound. I can't tell if it is the device or a neighbor's etc. It is not ever going to cause me to take it out of the wall. Before I bought these I saw three mice together playing family. Not one has been here since plugging these up. Don't crowd the area where you need this is. And try to use a shared wall it will save you money. Kindness is free if you can afford to. BUy at least 2 for your direct neighbor. I can't promise it is for the best.

These are marketed as being silent to humans and animals. My wife and I can both hear buzzing from all 3 units when they are plugged in.The night light function works; but, they are pretty bright if you are light sensitive while sleeping. They work fine in hallways to not ruin your vision and provide light; but, they are intended more for rooms than hallways.Now to performance. I put one in my garage. As a side note the product description says they are for small/normal size rooms. My garage certainly isn’t that. However. I put one out anyway as that is the intrusion point to my home for the mice; and because I could hear them buzzing inside I decided to try the one we removed from our bedroom.Fast forward to the next day I had an old Tom and Jerry style snap trap still out that was within 3 feet of the unit. My wife said she heard a snap and sure enough there was a fresh mouse in the trap right under the plugged in unit.I really wanted these to work, but, I think I learned the hard way that they’re gimmicky and not really functional for me.I don’t have the pack again; shame on me, so I can’t even return them to get my money back.Hope this helps someone avoid wasting their money.

I was leary about buying these repellents based on the reviews I had seen online, but after having a mouse blatantly walk over my bare foot, I became desperate. So far, so good. I have one in each room of my house and have not seen a mouse in months. Just in case you are worried about your pup, I have a small dog, and the ultrasonic noise does not seem to bother him. My only complaint is the blue nightlight; I wish there was a way to turn it off. There may be an option to buy these without that feature, but I did not realize that I could not turn it off before purchasing.

Really work , 1000% recommend by me .My Uncle ‘s house was infested by mouse , after buy this and plug one in each room , there are no more mouse or rat . You have to leave connected all the time , is you unplugged they will come back .

To start, 5 out 6 came working. This seems to be a common issue from other reviews. I had plugged them in when I got them and stepped out of the house. When I came back home, after 10 mins of being in the house I got a really bad headache. I thought I was getting sick. I know they emit a high frequency noise and wondered if that was the cause. After I unplugged them my headache went away. I came on here to read the reviews to see if anyone experienced the same thing and I found that I wasn’t the only one. I’m not sure if they work or not, they’ve only been plugged in for less then 24 hrs. but, my toddler also has sensitive ears and I’m worried they might experience these headaches too.. not sure if I will keep them in.

Easy to plug in discreet areas.

I have bought these 2x and since plugging them in I have seen any unwanted visitors
