Terrible black unfortunately! It does nothing, I bought two. They have it for 5 euros elsewhere. I should have read the comments, I hastily ordered them and they are useless

I just wasted 20 euros, I decided not to buy a very cheap training collar (5 euros) but neither 50 euros that my finances cannot afford. This particular one with 20 euros was somewhat in the middle. It didn't work, the fact that the light turns on and the fact that it shocks whenever it wants doesn't provide any training to the dog, it doesn't know what's happening to it and I applied it to a mixed breed like a Canadian Shepherd with a lot of fur and it didn't even notice. I tried everything at maximum and still nothing. Do not buy this specific one. In the store where you buy it, if you ask them if it does anything, all they tell you is that people buy this one. Well, we have a problem with our dogs when we leave but the issue is that afterwards we abandon it in the closet like I did, disappointed. I regret not buying something else for my dog with these 20 euros.

I have seen a difference in my dogs with the electric training collar, apart from the fact that they now know what it is and they are more focused in their training.

It is activated by the dog's sudden movement and not by barking, and the intensity it emits is very low, resulting in the dog not understanding anything

I do not recommend it. It does not work properly. It does not work with sound from barking but from vibrations. The dog can play and hit the power. It can sleep and also hit the power. Unacceptable.

It doesn't work. I bought it for two neighbors and they tried it for a few days each. The dogs had high nervousness, they were eating their legs and anything around (pots, etc.). And this is because the electricity is activated not by sound but by pressure (I saw it live, as soon as you touch it a little with your nail, you get shocked), so even if they drank water, it would activate.

I have a Caucasian Shepherd weighing 30 kilograms and it doesn't understand anything, so I can't imagine it being suitable for such weight

The collar is very good, I have been testing it for about a month. I have bought it for all four of my dogs. I am waiting to see the battery's power, it is very important. I also observe the dog's behavior during the barking control. It is important that the sensors stop the spikes' function at the right time so as not to cause panic to the dog. It should perceive the stimulus and not suffer. I am very satisfied and I would highly recommend it to those who would like to purchase a collar for their anti-bark dog. Its price corresponds to its reliability.

Initially good and effective. However, over time I noticed that the battery quickly drains and it also realizes when the dog is wearing it and continues barking when you take it off. It also breaks quickly, this is the third one I've bought (the second one broke in two months). It might be better if it had an audible warning.

Unacceptable, the battery dies in one day! And there is no charger! The battery inside is not rechargeable and you have to buy batteries every day! Stay away!

If properly installed and adjusted according to the size of the dog, it works perfectly and stops barking.
