This was my FIRST review - OUR FIRST WINTER WITH THE PRODUCT. SEE my SECOND review at the end of this one .. A YEAR LATER> I purchased this product for my family's 2 family house. My parents live on the 1st floor, I live on the 2nd. During the winter we were waking up everyday to "mouse droppings" all over the stove and counter, despite these places being washed down after dinner every night with Clorox lemon wipes. Peppermint oil being put on cotton balls and wiped on the counter is another thing we tried. After doing some research and talking to the people I decided this Ultrasonic Repeller was the way to go. I sent for them in mid-January. They arrived and we plugged in 2 on each floor. I feel I have been more then patient and have given this product a fair test (2 months). While there are fewer droppings, the mice are still here and still leaving their "little gifts". The light is blinking every 4-5 secs, since we can't hear the tone it supposedly gives off (sound that mice/bugs hate), I have to assume that either it doesn't bother the mice, they don't care or they are deaf or there is no tone and it is all a con because I can tell you -- These plugged in pieces of plastic are worthless pieces of garbage. THEY DO NOT WORK!SECOND REVIEW - I left the product plugged in for the year, it wasn't in my way. I did notice fewer spiders and those awful stink bugs. But the best surprise was the winter... NOT one mouse all winter long. From talking to people who have had these critters while the product does work, but it has to be in place and operating before the mice take refuge in your home for the winter. Once they are in and have their babies while the noise to them is horrible they can't leave. Which explains when the weather got nice they moved out and as long as the pest repeller stay plugged in they don't come back. We are now on our second winter, mouse free.

Seems to have worked as expected on every critter besides ants.

I recently purchased the Ultrasonic Pest Repeller for indoor use, aiming to address a growing issue with pests in my home. Here’s a detailed review of its performance and features. The pest repeller has a sleek and compact design, making it unobtrusive in any room. It plugs directly into a standard wall outlet, and its discreet appearance blends well with most home interiors. The build quality feels solid, with durable materials that suggest longevity. Since using the Ultrasonic Pest Repeller, I’ve noticed a marked reduction in the number of insects and pests in my home. It uses ultrasonic sound waves that are inaudible to humans but irritating to pests, which effectively drives them away. The device covers a reasonable area, though it’s recommended to use multiple units for larger spaces or multiple rooms.

For some reason last year we saw evidence of mice in our garage and we have never had that issue over 22 years. Previously we had the smaller plug in devices we got at a local hardware store. So assuming they had stopped working, I took a chance on these. No more evidence of mice so far and its been a year. Now, there could always be other factors involved but for the price - this is peace of mind.

I order these every 2 years and upgrade to new ones. That's how long I feel they are super effective. These work wonderfully. I don't ever see bugs or even a spider in my house. This is the only brand for this type of product I buy.

Recommended by family. First time purchase. Came in multi pak of 4. Purchasing another 4 pack.

First of all, it makes a clicking sound which is kind of annoying but you get used to it. However, they don’t work for mice. Oh well, I’ll try more traps.

I have bought several of these and keep them in my garage. They seem to work but not really sure. I have not seen any critters in the garage.
