Ultrasonic Rodent Repellent for Car Engines, 12V 24V Wired Ultrasonic Mouse and Rat Deterrent with LED Strobe Lights and Remote Control – Under Hood Animal Repeller for Cars, Trucks, RVs, Vehicles

well, it seems to be doing what it's supposed to do but, I won't know how effective it is for keeping the squirrels away for a couple of weeks.

Took my car in for an oil change and tech advised that there was quite a lot of rodent feces in the engine compartment. I bought some moth balls - but I couldn't stand the smell while driving. Bought this the next day. Hooked it up and every morning before leaving for work I open the hood to check for rodent activity. Now, a week later, I still see no evidence of unwanted residents in my engine compartment.I approve this little gem and would recommend it to anyone.

East set up. Worked as described.

So far it has kept the rodents out! Well the mice that was coming in vehicle no longer are in there!!

Works awesome no complaints

This item is a joke. It doesn't perform as designed. The instructions are not clear and they leave you wondering if it's working at all.

Easy install

I use to see little feet prints in the dust on the engine of my truck. Not anymore! I hosed off my engine and washed away all of the feet prints and bits of debris brought in by the rodents, waited for it to dry, then installed this device. Installation was straightforward and simple. We have field rats and pack rats here, they are a real problem, but with this device i’m seeing that the electrical components on my truck are now protected. Peace of mind!
