OYEFLY Handheld Dog Trainer, 3 in 1 with LED Flashlight,Bark Stopper Dog Trainer Devices Training Tool/Stop Barking(Black)

Ultrasonic sound stopped working after a couple of days of minimal use.
Stopped working after a couple of days. Only the light worked, no ultrasonic sound after two days of little use. When it worked had good results. I guess you get what you pay for, cheap.

Works too well.
This product worked well on my puppies but was way too much for their momma. It made her run away and hide. But I gave it to a friend of mine and it worked perfectly for her dogs

Kind of works.
It works as long as the dog is not deaf to this sound. Some dogs are deaf. Others can definitely here this. If they hear, they back off. Nice safety protection.

This is BY FAR the absolute BEST $8 that I have EVER spent!
Our new neighbor’s little corgi would bare teeth at the fence and act like Cujo on the attack. The barking was as if the owners were being slaughtered and the dog was made to watch. If the dog was in the back yard, this is how it acted at all times. My family could not enjoy the back yard AT ALL!!! I was at my wits end and had no clue what to do…then I saw this. I didn’t have high expectations for $8, but OMG!!! I purposely put black electrical tape over top of the light on the front, mostly because I didn’t want the neighbors to be aware of me using this high frequency device. That turned out to be a wise choice, because I feel as if the dog may have been able to figure out what was making the noise. As it stands, the very first time I ever used it the dog STOPPED immediately and looked aroung bewildered for a few seconds, then went back to his usual gnarly barking. I immediately pressed the button again for just a second and the dog turned around, scared, and ran for the back door porch and sat there QUIETLY! I had to use it for two more separate incidents, each with the exact same result. Since then, we do not have to use this device at all. The corgi is still not friendly, but it does not even so much as peep through the fence at any of us any more!

Works on strays, did NOT work on home pets and trained dogs, same thing with stray cats, worked on them but not home cats… so, 50/50 in my case.Was great help to get rid of strays around the parking lot when we were abroad this summer in eastern Europe.

We recently rescued a little Pomeranian cross who is very noisy and loves the sound of his own voice.Now I’m a dog lover, and I know that dogs like to speak their minds at times – but lets face it, there’s appropriate barking and then there’s inappropriate barking, and this little guy definitely prefers the latter sort. Especially when out for a walk and he spots another dog, a cat, a person, a leaf falling from a tree, or if he hears a bumble bee farting two counties away. It was next to impossible to stop him once he’d started.We don’t blame the wee guy. He’s a rescue, so god knows what kind of trauma he’s been through, and I know that most inappropriate barking is caused by fear. We just needed to find a way to distract him in the moment when he was in a frenzy, so we could then reward him, make him feel safe and reinforce that no-barking behaviour.Believe me, we tried everything.Then I saw this device mentioned and advertised on a dog training forum. It was just under £50, and I’d have been happy to pay that if I knew for certain it would work.So I did as I always do and looked on Amazon to see if I could find any better prices for the same thing or something similar.Well, blow me, but I found this one.Seemingly the exact same device, but without a fancy brand name badge, and with a price tag of around ten quid.I got it ordered and it arrived the next day. Took the wee man out for a walk to test it, and we had INSTANT results.I honestly couldn’t believe it.At the first sign of a growl or a yelp, just blip the button and the wee guy stops instantly and looks around him with a look of confusion, as if he’s saying “what the heck was that? did anyone else hear that?”.To human ears it’s absolutely silent, but to my wee pooches ears it must be as loud as a brass band.This thing is incredible. It’s about the size of a Firestick TV remote, so I now have a remote controller for my TV and for my dog.If you’re having behavioural issues with a dog, I highly recommend this little device.Honestly, can’t give this review enough stars.
