4-in-1 Ultrasonic Rodent Repellent Plug-in Mice Repeller Rat Deterrent Pest Control Device with Ultrasound, Impulse, Flashing Lights, Predator Sounds, Indoor Mouse and Rat Control, Pack of 2

I wasn't sure if these would work but I decided to give them a shot. I had tried everything else so why not these. Peppermint oil, rodent sprays, moth balls, etc. None of these worked to keep rodents from nesting under the hood of my car. I have a company vehicle I drive so my personal vehicle sits in the garage for 5-6 days straight which the rodents love. I bought a 2 pack of these and put one by each front tire. One mis set to the predator noises and the other on the high frequency sounds. Both units have the lights activated. Since I started using these I haven't had any rodent issues. No signs of the rodents themselves or acorns that they loved to store on the top of the engine! These devices pleasantly surprised me. I had just about given up evicting these creatures. If I knew these would work that well I would have bought them a long time ago and saved $ not buying sprays, oils, and mothballs.

Works great as far as we know. But one of the two units stopped working after 10 months. The info that came with it said it had a 1 year warranty so we wrote to the vender per Amazon. We could not believe it when we received a replacement unit within 3 days!

It affected my dogs badly doesn’t deter rodents what so ever I gave it an opportunity to work but to no avail it didn’t

I have 6 of these, 4 in sheds, one under my hot tub, and one in my grill. Have been using them for over a year and they definitely keep mice away.

Bought 4 of these units for my garage, shop and trailer. Seems to be working great . You can adjust the volume when you place them away from your house.

it is a pc chip like on a card, so I think it is too much money, but it does work no birds on my roof chased them away

Received last night. Plugged it in in the garage, started fiddling with the mode switch. When I switched it from TEST to Ultrasonic, as I stood there, I almost immediately heard a frantic rustling noise in the corner. Within 15 seconds, a mouse shot out of the garage door. Ordering 2 more after writing this review.

I have bought three of this device recently. I have put one in attic and one in garage so far. My attic camera has seen one big rat moving around and making annoying scratching sounds freely even at higher sound settings of various species. The sounds were quite annoying to our ears. Then I bought $50 rat zapper very recently and activated it with some peanut butter as directed and within 2 hours the big rat was zapped and disposed. So I would have to say the money spent on this Loraffe device did not give me the positive results. The device did come promptly and in good condition.
