2025 Upgraded Bat Repellent Deterrent Ultrasonic

It’s working! I bought a package of four, and probably 2 would have done the job. Love that they are rechargeable. Using one in a gazebo in the woods. Love that I can change the frequency. Thank you!

Does quickly. Doesn’t hold charge long.

Bats bats bats… finally thinning the heard! This product works once you (by chance) find the right frequency. With bats the frequency is very high and since the instructions are awful it’s hit and miss. Ironically the setting turned out to be opposite (turning to the lowest setting left rather than raising to the right). Since it’s inaudible you have to guess. Despite working after about a week I dropped a star both for bad instructions and very limited battery life, three days max before having to recharge.

Needs to be charged every week

I purchased 2 sets of 4 units of these items. They all have the same issue. You turn them on and they emit their sounds as advertised. In a few days after they are on they shut themselves off. You can push the button and turn them on again as the battery isn't discharged. They just won't stay turned on for the duration of their battery life.
