This device does not feel cheap or flimsy. It works well and is not complicated to use. It is not our first experience with a dog deterrent device, but it is the best one by far. We have purchased a few different dog deterrents. Before we had our dogs, we were surrounded by neighbors with multiple dogs that liked to bark a lot. We bought a Seicosy Weatherproof Indoor/Outdoor Pest Repellent & Ultrasonic Bark Control for Dogs, basically a plug-in dog deterrent box, from Amazon & put it on our back patio. It was supposed to emit a noise whenever a dog barked incessantly, but we doubt that it worked because the dogs kept barking. When our rescued Boxer mix was no longer a puppy, we bought a Remeel Dog Whistle from Amazon to deter her from digging in the yard and to curb her barking in response to the barking neighbor dogs. It worked at the moment but made no difference in the long run because, until we blew the whistle, she continued repeating the unwanted barking whenever she was outside. [On a side note, we got her to stop digging by burying her poop where she was digging. I thought that the idea was absolutely crazy and was doubted that it would work but am so glad that it did.] Later that year, we rescued an older, long-haired Chihuahua who was not fixed, house-broken, or trained in any way; he had “small dog” syndrome, barked a lot, peed on everything, and marked his territory even after he was fixed. When I came across the Mimill Handheld Dog Repellent Ultrasonic Infrared Dog Deterrent similar to this one, I bought it. Of course, I was skeptical of this one, too, but I could tell that each dog knew when the button was pushed and if it was pushed for him or her. The only problem was that since it was our only device, it was “lost” frequently because someone would use and set it down in a different location, causing a mad search when it was needed. At the end of the day, I was tired of hunting it down and bought a Brellavi just for me. The Brellavi device is kept by the back door to be used when the dogs are outside. I prefer the Brellavi over the Mimill because it works better and is visually more appealing (doesn't look like a repurposed taser). For our boxer mix, I show it to her before letting her in the backyard, and she tends to not run straight for the fence, but if she does, I click it and make her come inside. For our long-haired Chihuahua, we use it when he goes “psycho-huahua,” incessantly barking his head off at anyone or anything or growling. As an added benefit, it also works on the neighbors’ dogs who bark whenever they are outside. We also use the Brellavi to break bad habits. For example, since the Chihuahua was not housebroken when we rescued him, he would cock his leg to pee wherever. At first, we were ecstatic when he pottied outside instead of inside the house. We would open the door & say, “Go pee on something, anything; just go pee outside,” but he preferred to pee on the covered patio which was not what we wanted instead of the grass which is what we wanted. Now, when he goes outside, I hold the device, and if he cocks his leg on the patio or deck, I click it, he looks up and runs into the grass to potty. Phew! The Brellavi Anti-Bark Dog Training Equipment and Barking Control Device is user-friendly and effective. It is money well spent. We highly recommend it.

My dog is a barker and he literally barks at just about anything outside our home. People walking their dogs, cars going by and especially our neighbor and their dog. We share a dance and my dog literally stares at their house waiting to bark at them. We have tried non-shocking bark collars and they worked but I hated leaving it on him all day and night, plus I had to keep changing the batteries. A neighbor told us about this device that she had bought for her dogs who had similar issues and we decided to give it a shot. I saw immediate results. The first time he started barking at the neighbor, I hit the button and it got his attention and he stopped. I gave him a correction of No and come and he immediately retreated to my side.The next day I was working from home like so many people and he started barking at something outside and I pointed it up at the floor (I was in the basement and he was upstairs) and hit the button and gave the command of no. He stopped barking and within seconds was at my feet.This thing is phenomenal. I’ve recommended it to others with dogs.One bonus is that you can also use it on the jerky dogs at other homes. We happened to be out walking one day and I forgot it was in my pocket and a neighbors dog started barking at us. The owner wasn’t correcting it or trying to get it to stop so out of curiosity I hit the button from my jacket pocket and the dog stopped. It really gets their attention so they stop barking.I highly recommend this as a training tool for your dog. It is a great value and so easy to use.

Update. We've had it 9 months. The dog is not bothered in the least by the sound or flashlight. We don't use the high setting because we do not want to BLIND OUR DOG by shining a LASER into his eyes. Moronic product do not buy.It has three settings. Flashlight because why not. That's fine. Then two levels of "control". The lower setting, I, it has a mildly strobing light, and I assume the sound. It does work on our dog. I have tried others that only scared off our cats. So this is a better one. The dog is not scared; it's not intense enough. He just looks annoyed or confused and strolls away.My only beef is the higher control setting. At II it has a red lazer! Why?!? You use this device by pointing it at the dog. So you'd be pointing a lazer directly at the animals eyes. Which could DAMAGE THEIR EYES. If I'm going to need that level of force, I'll use a weapon or spray, not this silly thing. So I'll never be using the high setting. Fortunately the lower setting seems to do the job, so just use that.

This product is a glorified torch. The sound is no where near ultrasonic and sounds like a house alarm, it doesn't work in the slightest and you can't actually turn it on without 3 dumb torch settings being activated, including a illegal red laser. Waste of money...
