It keeps the critters away.

I bought this for my Lexus which is leased. I replaced the windshield wiper fluid and when I went to use it, nothing came out. I was scheduled for a check-up at Lexus so I took it in the next day. They called me two days later to tell me I had a bill of $13,430.00. I almost had a nervous breakdown. What could possibly be wrong and what would cost that much to repair? My car is always in the garage when it's not being driven and I've lived here over 20 years without any problems. They told me a rat ate the inside of my engine and chewed through the wiring, etc. A RAT???????? I was so confused -- why would a rat eat my wiring and how did it get in there when I drive at least once a day. OK, maybe there are weeks that I don't drive for two days in a row, but that is rare. Why didn't it happen during the quarantine when the car rarely moved? And how was the car driving with so much damage? Lots of questions. So, the first thing I did was call my insurance company, freaking out the whole time thinking they aren't going to pay for some rat eating my car. The second thing I did was research why a rat would want to eat my engine and boy, was I surprised. It had been very cold where I live -- unusual it would ever be below mid-high 40's ever -- but it had been in 30's for many nights during the winter. Then I discovered that Toyota, who owns Lexus, had replaced their wiring for environmental protection reasons. The only problem with that is the rats and mice find the new material very enticing and love to eat it. Apparently, Nissan is aware of this problem and from what I understand, they wrap some type of tape around all the wiring that tastes like hot peppers. I guess the critters don't like that. I've been told you can buy this and wrap your own wiring but I can't imagine what a job that would be. Sheesh!! Thankfully, my insurance paid for every penny of my repair but I don't know if they would do that again -- thus, this device. Of course, now its summer but I went through winter without anymore problems so I'm guessing it's because of this. As far as I'm concerned, this has kept all the critters out of my engine and I would try it if you have had this issue or don't want to have this issue.

So far it works good after cleaning the engine haven't seen anything yet still testing...

This works fabulously! I am thrilled! I tried EVERYTHING else I could find or use "do it yourself" and nothing kept the mice out of my car. UNTIL this. Painless to use--goes on automatically with any motion near the car. Undetectable unless you walk into a dark garage and you see the flashing light. BUT it works VERY well. NO MICE at all!

Purchased 2 of the Loraffe Under Hood Animal Repeller Rodent Repellent devices. One in June of 2020 and another in Oct 2020. Both devices are under hood of same car. They are still working as of Oct 14, 2023. Lights still flash brightly. Installed due to raccoons constantly crawling into engine bay and causing damage. No raccoon activity under hood since installing.
