Vibration as well is awesome when the dogs need that extra reminder to stop what they are doing.

I love this collar. I bought two. The beep and the vibration buttons do the job. My dogs come running when they hear the beep. I’ve charged them once since receiving them. They have helped make life around here more peaceful with well a behaved Great Dane and Aussie��

Works great battery last days if you just use it while training

Its a big help so far in training our dog. Thankful for finding this when we did.

Ease of use hland holds charge very well.

I am enjoying this product so far!
