Haven't tried them yet. That is why I'm giving it 4 stars

It helps against critter and works fine.

good 👍

It works Our particular garage is hard to get remote. Cannot be bought at regular big box stores. We host Airbnb in our home people have damaged remotes accidently I am sure often not telling us only to find out after they leave.

I bought and used these this past winter in our camper....first time that we haven’t found a dead mouse or droppings. Will definitely use these again next winter....would recommend to anyone that has problems with mice.

My Buick LeSabre vehicle has been attacked by mice, and/or squirrels, and/or birds three winters in a row. Yes and one time it cost me over $500 to have the car rewired. Tried this unit in December 2020. Did a thorough cleaning of engine compartment and removed all droppings prior to installation. Just checked after 3 months and no rodent, bird, squirrel, activity at all. Just changed out the batteries ... will probably do rechargeable one next changeout. Very happy with product. I should say I have also tried mint spray, Pine Sol, and Dryer sheets but this unit gave the best results.
