Victor M753SN-1 3-Pack Mini PestChaser Rodent Repeller, White

After trying multiple brands, this is the only brand I found that worked to get rid of my mice. I highly recommend!

My Mom was having a hard time with mice in her house. She lives in an older home near a wooded area and they were finding their way inside. She hated dealing with traditional mouse traps and wasn't having much luck actually catching them, aside from the nasty task of disposal when she did get one. My husband plugged these in at our shop and the mouse problem stopped so I suggested these and had them sent to her. If they really did work, I know she would be the true test. Trust me, I saw the surprise nests in her closet and basement. I just ordered another 3 for her because she can't believe they're gone! She now swears by these things and wanted more to plug into her garage and other rooms in her house. Will buy more as needed.

I bought an RV that the previous owner has told me had a mouse issue at one point. That was clearly false because right after I bought it and went to sleep in the master bedroom, I heard scratching in the wall by my head. If I banged on it, it would stop for a couple minutes. This went on for 3 nights. I ended up buying these and luckily there are outlets on both sides of the bed right next to the wall where the noise was coming from each night. I installed 2 of them, one on each side of the bed at noon that day. It's now midnight and they have been running 12 hours and I can't hear any scratching tonight.I will say, I can hear a very slight "hum" coming from the two that have the red LED lights. The one with the night light, I can't hear anything from. So to say that humans can't hear these is false, and other people say they can also hear them. It isn't loud, just a very light hum... Almost like when a lot of electricity is running through a power line above you.Also they say they don't work through walls, but I don't hear the scratching from inside the wall anymore. Maybe because RV walls are thin, or maybe because I installed two of them right near eachother and they are very close to the source of scratching? Not sure.I will update this review though if they seem to not work at some point.

So far, so good. I haven't seen any "visitors" at work after plugging them into the power strips.

The manufacturer claims that one unit protects 400 sq-ft of living space. I have a ~240 sq-ft camper/trailer that mice love to live in despite all my efforts to seal up tighter than a drum. There is NO food and NO water in the camper when stored - but the mice invade anyway. I installed TWO (2) of these in the camper over a year ago - with NO discernable decrease in mouse activity. I trap/kill the same number of mice now as I did before. I also installed one on these in my garage, directly in front of my car (less than 8 feet from the hood), that did not stop rodents from building a nest in my engine compartment and chewing up insulation and hose lines. These do NOT work, at least not in Arizona!

I purchased this a few months ago. Seems to work but it emits A slight hum that we can’t bear. Also, the light is too bright. I couldn’t find these without a light.I’ll be looking for replacements soon.

I wanted to wait a while before leaving a review. I bought these 2 months ago and I haven’t seen a single mouse! We live on 8 acres of land so we had a huge problem with field mice. I got these plugs and I haven’t seen a single one since. Just to be sure I bought a bunch on sticky traps and they’ve been untouched for 2 months.

Maybe I have really good hearing but I can hear a buzzing from it and it gave me an immediate headache. I haven't seen any difference so I can't say if it works or not.
