Funciona, pero hay momentos que no llega y no es oído por el can

I found it was time to train on my dog's misbehaved barking. We are still in the beginning phase but found improvement in the barking. I think the device is easy to use and has many options to train with. I like that it doesn't take batteries, all I have to do is recharge after it dies.

The Yorkie mix does not often bark without good reason. The Pomeranian and Shitzu mix with excessive hair is causing most of the nuisance. He barks at everything on TV, any noise, and people walking by outside. At any time, whether day or night. I informed my wife that I am considering parting with him soon. To calm him down at night, she places him on our bed. We experimented with the shock dog collar on our dog, but it appeared to be cruel. Additionally, he had become resistant to the shocks, making it unbearable to increase the level.This M-239 model drastically reduced our dog's barking during the initial attempt, and he stops barking altogether just by confronting it.The first ultrasonic frequency is at 25KHz with a low decibel range.The second ultrasonic frequency is at 25KHz with a high decibel level.The third ultrasonic frequency ranges from 24 to 26 KHz, with a rolling pattern.So far, we have only used the first frequency, and the results have been satisfactory.The flashlight is not that important to me. The main reason for buying this device was the unique frequency, so the dog does not become immune.Additionally, it is important to note that when we attempt to discipline the barking Pomeranian mix, the Yorkie mix also gets unintentionally provoked as she is within the same vicinity. The range of the device is 16.4ft in an open space and is reduced when walls and wall materials are present. For example. Wood and sheetrock are more porous for wireless signals while concrete is less porous, resulting in a shorter distance for signals.

I Prefer this to the whistles even if is larger. I can't put on my keychain but I could definitely tell it works. It has an easy to read digital screen and its much easier to adjust the frequency. A flashlight built in is a bonus. My Mom's dog would bark the whole time her nurses were here. It was stressful and embarassing. I had to do something. He quickly adapted to it and understood what was being asked of him. We have much better visits. I am disapointed that everything needs charged now a days as I have mentioned in previous reviews. Besides my phone, I do not remember to charge all these things. Then there is a wait for it to fully charge. I would prefer batteries or atleast rechargeable batteres that I can have charged in advance.

My dogs responded to this the very first time I pressed the button! I have 6 little dogs and when they start barking it's hard to get their attention but with this it only takes a short button press and they stop barking!!!
