Took forever to arrive & this shipper won’t go out of his way if it goes missing & stops responding to messages so I don’t recommend this seller but the product is good.

works perfectly!! the young labrador puppy stopped barking early in the morning from the first day we used it. Great product!

Very quick delivery. this works very good ,very satisfied, thank you,I will Orde a second one for friends

It is very effective. After opening, the dog no longer barks, the package is very fast. Thank you seller

Was a bit skeptical about this but it actually works! My dogs stopped barking within minutes!
