Review on 🐶 OYEFLY Handheld Dog Trainer: 3-in-1 LED Flashlight, Bark Stopper & Training Tool (Yellow) by Megan Hartman

I had the exact same thing but it seems to be a different brand. Took about 6 months but several times I threw it away. The light still worked, but the buzz didn't work. They're thin, but they keep my dachshunds from barking and redirect my dogs' excited barking when guests arrive. I can usually get them to stick with it after a few beeps. It usually works in the middle position, but sometimes I use the last buzz. Sometimes only the first position light catches their attention and diverts it. Works for our 2 doxies.
