Excellent product, very easy to use and extremely effective. Different levels of intensity make for an effective tool regardless of dogs age or size. I contacted the seller about buying separate accessories and was answered in a matter of ours. Accessories couldn’t be found so the seller sent another kit free of charge! Great experience all around.

this is a lifesaver. I have dogs that bark and even though trained, apparently not good enough lol. my neighbors dog gets to him. vibration mode is all I need
