للأسف لايؤثر كثيراً كما حل بقية الأجهزه من هذا النوع تحتاج تلك الأجهزه إلى قوة موجات من 4 إلى 5 أضعاف قوتها حتى تؤدي الغرض ويقال عنها جيدة. نصيحتي هي أن لا يهدر المال على أجهزه لاتجدي لمجرد مايقال عنها من قبل المتاجر أو الثقة في التعليقات هذا رأيي الخاص بعد التجربة دون تحمل أدنى مسئولية في مواجهة الغير.

First of all I want to state that you don't have to use it often and you don't have to press the button for very long, a very quick press is all you need! Because it does bother their ears! And please don't let it get into the hands of children because they won't hear it and they will keep pressing it and possibly put it right up to a dog's ear or cat and it will deafen them. That being said it works! I have two very reactive dogs and instead of barking or going towards dogs and people they now come toward us instead when dogs are barking or when people are approaching which is exactly what you want. The key is timing and again don't overuse it! One of our dogs is actually afraid of it so we try not to use it too often. Another thing to note is one of our dogs barks when she is happy so you have to be careful when you use it because you don't want her to not be happy. In short it works just use with caution!
