Dogtra YS600
About 4 year ago I bought a SBC-10R bark collar from bark control Australia for a Malinois, within six months the battery wires broke inside the bark collar so I replaced it, by the end of the year the push button to turn the collar on had come off although you could turn still turn it on. I like the pulse option on the Dogtra for training and appears robust with manual control. I am a believer KISS ( keep it simple stupid) as I find the more automatic options the collar may have the less control you have over when and how your dog recive corrections. I purchased an additional 2 Malinois pups this year and would purchase additional collars from bark control Australia.
