Description exact, delivered in 15 days to Ukraine by new mail. I haven't tried the dogs yet.

It works, animals react to the emitted sound wave, not that they run off but stop barking.

The device is very good, small and medium dogs repels, it has not tried on large yet

Very good product, it serves to train your dog or the s-dog to stay away for safety.

The sound is heard well, unpleasant even to me, on dogs did not check yet
