Masbrill 5-in-1 Ultrasonic Dog Training & Anti-Bark System: Humane Bark Deterrent & Behavior Corrector-TZ935

This device works amazingly well. It��s easy to use, very effective, and the quality feels solid. I noticed results right away. Highly recommend!

This will stop your dog from barking endlessly.Works incredibly well without harming the dog.My dog is a super loud barker and one beep from this and he stops. Highly recommended.

This device works really well to stop unwanted barking. The ultrasonic sound gets my dog��s attention quickly without hurting him, and the flashlight is a nice bonus. It��s easy to use, lightweight, and effective both indoors and outdoors. Great humane option for training!

The product looks good, I recommend it. It's also rechargeable and has a long-lasting battery; it definitely lives up to its promises.

This is just the ticket for training your dogs and breaking any bad habits they have. Has the warning which gets their attention and then the sound to curb the unwanted behaviour. It does not hurt them and I cannot hear it but it sure does work. We had a teacup Schnauzer that would lose her mind when strangers came into the house. Would not stop barking and growling no matter what. This solved that quickly. Now if she forgets, all I have to do is let her see the the trainer and she remembers.

Excellent product, I recommend it for silencing your dogs or the neighbor's dogs when they are being too noisy.

The color is the same as in the photo and it's working as expected for my pet's training.

Amazing Anti-Bark Device �� It Really Works!I am very impressed with this 2025 dog anti-bark deterrent device. The ultrasonic range is excellent �� it truly reaches up to 65 feet, which makes it perfect for both indoor and outdoor use. Within just a few uses, I noticed a big improvement in my dog��s behavior. It redirects their attention without causing any pain or stress, making it a much more humane option than traditional training collars. The device is easy to use, lightweight, and effective even with stubborn barkers. I highly recommend it to anyone looking for a safe and reliable solution to excessive barking!

It arrived super fast, the flashlight has very good light and the dogs obey the sound

Great training tool

Definitely works for that noisy dog in your apartment complex

This device works way better than I expected. It helps calm down loud barking fast without hurting the dog. It��s easy to use, lightweight, and the battery lasts well. Simple and effective �� does exactly what I needed

I was hesitant to purchase but was at my wits end with our Basset not listening. 1 week and by day 4 all I had to do was show it to him. By the end of the week I didn't even had to touch it. No pain no noise but enought to catch his attention and make him pause.

I have tried several barking solutions, and the MASBRILL deterrent is the first one that really made a difference. The 65FT range works great for outdoor training, and it reacts right away when my dog starts barking. After a week, I saw a big improvement. He is calmer, more focused, and no longer barking at every person who walks by. It is lightweight, easy to use, and completely humane. If you are dealing with stubborn barking, this is the answer.

this product very awesome , works very good

Works great

A very good device. Easy to use. Very good size. My dog already know it ??. Value the money.

Excellent, works like a charm.

I noticed a significant difference immediately! This Anti-Bark Device is powerful enough for my dog ??to hear even 20 meters away. It makes controlling his excessive barking so much easier. It's portable, easy to charge, and discreet. It's a much better and safer way to train than electric shock collars.

This device i order because I wanted it for a gift and i like it the quality is excelent.

Very effective and easy to use!This ultrasonic dog repeller works great! The sound is strong enough to stop barking or aggressive behavior without harming the dogs. I also like the bright light feature for nighttime walks. Compact, rechargeable, and simple to operate �� perfect for daily training and extra safety outdoors.

Safe and effective

Works great! Dogs hate it. Use it in the short term, but combine it with other trainings so you don't have to use it forever.

It actually work!!! And good quality

I bought this device on November 1, 2025, and I��m honestly impressed. My dog used to bark constantly, especially when people walked by the house, but after just a few days of using this device, the barking has reduced a lot.It��s very easy to use, with several ultrasonic sound levels and a built-in flashlight that��s super handy for evening walks. I also love that it��s a humane alternative to shock collars �� it doesn��t cause any pain or stress to the dog.The battery lasts a long time, and the 65-foot range works great both indoors and outdoors. The design feels sturdy, lightweight, and comfortable to hold.Overall, this is an excellent tool to help stop excessive barking or for positive dog training. I totally recommend it, especially if you have a stubborn or hard-to-train pup.?Would you like me to make it sound a bit shorter and more casual (like a quick MASBRILL review) or keep this full version?
