STÙNICK SB3 Dog Bark Deterrent Device Stops Bad Behavior

It's been working well. Our frenchie is hyper sensitive and barks at everyone and everything. Sadly the other animals in the house need to endure the sound with his current behaviors, but it works at stopping it instantly.

After 6 years of our dog going bonkers barking like crazy when people came to the door, this device worked to quiet him instantaneously.

Works good. The dogs respond. The only reason for a 4 and not 5 stars is theirs no way for the light to stay on, it just flashes while using the device for the dogs. As a device for my dogs it's great, however I feel it's a mistake to have lights that flash while using but no ability to keep it on while walking the dogs. Seems like a pretty big oversight because I need to bring a flashlight as well as the device instead of an all in one.
