Bests & Worsts Reviews from Amazon

I ordered this out of desperation as my neighbors have 2 small dogs and they bark solid for 30+ min at a time at least 4 or 5 times a day. I mentioned it them when i met them but they don't seem to care. This device stops them in less than 1 minute...about 6 or 7 presses. I never use it unless they are barking b/c I don't want to confuse them I want to train them. The best part I am training their dogs and they have no idea!!!! Nice to have the upper hand in this situation. This has worked literally every single time within one minute.
