lo use para que no se metieran las ardillas en el motor del automovil y a la fecha ya no he visto muestras de que se sigan metiendo.

Easy to install. Put 1 under the hood and in the trunk. Removed the mice and they have not returned.

My 3 vehicles, parked on my driveway, have had consistent evidence of mouse habitation; mostly acorn bits and droppings in the Cabin Air Filter Housings. This spring, I had mice chew through several critical engine wiring harnesses on my Sedona resulting in major repair costs.I bought one Angveirt Repeller per car and checked the cabin filters weekly to see if the mice were 'repelled'. I used Eneloop AA Rechargeable batteries for power. They installed easily with velcro adhesive strips in the Engine Compartments in a cool location which had evidence of mouse debri.For good measure, I also sprayed the engine compartment with Peppermint Oil and added Mice poisoned bait traps under the car and on the opposite side of the engine compartment.The results after 6 weeks of use:1. Units LED/Ultrasonic units work for at least 4 weeks on a charge.2. Mice still occupy my cabin filters. (They need to climb up into the engine compartments to get in).3. Mice were not tempted by the Bait adjacent to the Repeller and did not seem to chew any Peppermint flavored wires.4. The mice seem to want a dry, safe nesting site and probably tend to enter the vehicles if the cars are left idle for more than a day or so.My verdict is that a combined approach and daily monitoring is needed to control the mice problem.The mice are finally nibbling at the bait traps under the car and I hope that this eliminates the local population.January 2021 Update. Upgraded rating to 4 stars: Monthly inspections have shown no evidence of Rodent activity in my 3 autos parked outdoors. My key take-aways are:1. A combination of poison-bait traps, Peppermint Oil spraying and the Angveirt Repellant kept rodents out of my autos. The last 4 monthly checks showed zero droppings in my cabin air filters.2. My 3 Angveirt Repellent units have worked flawlessly for 7 months. The 3 AA Eneloop NiMH batteries in each unit kept the units operating for a full month between recharges.

Wanted to wait to see if this worked to keep the rodents away from my car or not before writing a review....Overall, this seem to work better than the Peppermint pouches...The rats never returned to either car, whereas with the peppermint pouches, the rats got used to it after a week and started building its' nests again on top of the engine cover. My reason for the one star is that both devices stopped working within days of each other. I had it in my car for less than two months and both stopped working about the same time. Thought it was just the batteries, but it was not. Pretty expensive for something to crap out after only about a month and half.

We have these in two cars that have been infested with mice. We had a Tesla in for repairs twice and a Prius that always had a nest on the air filter. Since using these for almost a year, problem solved! Just a couple of droppings here and there. They do use AA batteries fairly fast, though.
