Electronic Pest Repeller, Ultrasonic Mice Repellent 4 Pieces for Home and Business, Plug in Pest Control Against Roaches, Mosquitoes, Flies by Ansbro

These devices work for mice and I have not seen any in my home or condo where they are plugged in since I began using them (over a year ago). There are much fewer insects in my downstairs area, where I would see all kinds of varieties all of the time. This does not eliminated bugs, but there is definitely a reduction. They are in every room in my home and the sound does not seem to bother my dog in any way.

Wow! This item really works fast I had a tricky little mouse who stayed hidden for weeks, it jumped over glue traps and wouldn't eat the bait I finally found a product that works and capture was complete in one day after turning it on. Thanks!

Doesnt work at all.. Since i placed them in my home, 2 per room. Ive seen flies, stink bugs and witnessed a mouse run right underneath... Definitely a waste of money. Installed for over 2 weeks now.

One makes a weird sound and seller never responded to my question. Plus I trapped a mouse 2 feet away from the product.

Two of the four units died after 1 month. The other two are still going strong after 6 months now

Don't waste your money! I bought this product in May and installed according to directions and still have mice. This product is nothing but a glorified nightlight.

the best i bye

2 came damaged and not really sure if the work (the bugs where laying on top of it...) :(
