"Initially, I was skeptical about its effectiveness, but I haven't seen any rodents nearby since using it for quite some time. It's incredibly easy to use and compact, so I hardly notice it."

"I found this ultrasonic repeller to be a great addition to my home. After plugging it in following signs of rodent activity, I noticed no further evidence of mice after a few weeks. It operates silently, allowing me to enjoy peace of mind without the need for harmful chemicals."

"This device seems to work, but I had to cover the sensors and push the LED button for the flashers to activate. I believe the flashers contribute to its effectiveness. This is my fourth unit as I keep adding them in different locations."

"I live in an apartment and have had this product for just over a month, but I still see roaches. While I haven’t spotted any mice, it’s disappointing to see more baby roaches than before. This product doesn’t seem to work well for apartments with serious pest issues."

"After using this for three weeks, I can confidently say there’s been no effect. Mice are still present, and the only way I've managed to catch them is with sticky traps."

"Initially, it worked well but then the rats got used to it. I’ve noticed my pets were a bit agitated at first, which makes me wonder if the rats will adapt too."

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

"I bought this for my off-the-grid cabin, expecting it to work just like my plug-in devices. Initially, the mice ignored it, but after some time, the cabin is now clear of mice. I've also used other methods, like dryer sheets, but I'm planning to order another unit to ensure continuous protection."

"I placed this device in my attic after months of scratching noises. To my surprise, the scratching stopped the very first night! I’ve had plug-ins in my main living area for years, but this has been effective in the attic as well. I'm now getting additional devices for other parts of the house."

"I am very satisfied with this ultrasonic animal repeller! The expulsion range is incredibly wide, covering a large area. Its eviction effect lasts a long time, which is impressive."

"The user-friendly design and variety of working modes make it easy to customize according to my needs. Plus, it looks beautiful and doesn't disrupt the surrounding environment!"

"I appreciate that it can draw power from three different sources. I chose USB to save on batteries, but I might use batteries if the outlet is out of reach. We've had rodents sneaking in, so I'm hopeful this device will keep them out. It has solid construction and seems durable."

"Initially, I placed this in the garage because I was bothered by rattling noises. For a few days, the noise stopped, so I'm considering moving it outside in front of the house to see if it works there as well."

"In my experience, this repeller is too loud for indoor use, which bothers my cats and us humans nearby.

After only a few days of use, I've noticed that the mice and cockroaches around me have significantly decreased, nearly disappeared. Plus, it's non-toxic, chemical-free, and requires no maintenance like traps do. It's a great solution for anyone seeking a safe, simple, and effective rodent repellent."
